Much of our medical research data from animal tests may not reflect reality, except of that of fearful stressed out animals. It will skew any and all results gained thereof, however.

The biology of animal stress By Gary P. Moberg, Joy A. Mench
The subjects of stress and animal welfare are currently attracting immense interest. The purpose of this book is to bring together a range of perspectives from biomedical research (including human health and animal models of human stress) on stress and welfare, and to assess new approaches to conceptualising and alleviating stress. Contributors include leading authorities from North America, Europe and Australia.

And speaking of the National Academy of Sciences, they recently released a groundbreaking report calling for what is, essentially, the end of animal testing. Though it's not likely to happen soon, the NAS report calls for more reliance on in vitro and in silico (computer modeling) methods to determine toxicity or lack thereof and a shift away from using animal models.
In recent decades there has been a distressing decline in the numbers of healthy volunteers who participate in clinical trials [7], a decline that has the potential to become a key rate-limiting factor in vaccine development. Reasons for this decline are unclear but are likely to be multifaceted. One familiar problem is the payment of volunteers [8]. To date, the relatively meagre compensation that participants often receive could be seen to belittle and undervalue the contribution of these individuals to global health. The modest financial remuneration commonly provided often means that students and the unemployed make up the bulk of volunteers [6, 8, 9]. As a result, the risks of developing a health intervention that would benefit the whole population are carried disproportionately by some of society’s most poor and vulnerable. This is a situation few would judge to be fair or ethical. However it is hard to increase volunteer payment without creating financial incentives. “Danger money” is frowned upon as an inducement that inevitably clouds an individual’s appreciation of risk, limiting the likelihood that consent is informed [6, 7]. As a result, consensus has generally dictated that payment for volunteers’ trial involvement be modest and limited to compensation for travel, time, and inconvenience only.
If progression of promising vaccines from the lab to the clinic is to remain unaffected and financial inducement is an ethically unacceptable solution to the recruitment shortage, other strategies need to be considered. Compulsory involvement in vaccine studies is one alternative solution that is not as outlandish as it might seem on first consideration. Many societies already mandate that citizens undertake activities for the good of society; in several European countries registration for organ-donation has switched from “opt-in” (the current U.S. system) to “opt-out” systems (in which those who do not specifically register as nondonors are presumed to consent to donation) [10], and most societies expect citizens to undertake jury service when called upon. In these examples, the risks or inconvenience to an individual are usually limited and minor. Mandatory involvement in vaccine trials is therefore perhaps more akin to military conscription, a policy operating today in 66 countries. In both conscription and obligatory trial participation, individuals have little or no choice regarding involvement and face inherent risks over which they have no control, all for the greater good of society.

I sang and danced just a wee bit.
They diagnosed me hypomanic.
Now they are in the process of forcing me to take anti psychotic medication (http://en.wikipedia.org/wiki/Olanzapine).
It's a travesty.
But I do feel like I am being forced to swallow my last vestige of pride. I have always opposed forced medication on the unwilling, on philosophical and religous and political grounds. My wife knows and understands this, yet she is supporting the doctors and is insisting that I take the medication.

All praise the buddhist doctor who appeared on my path!
He rubbed out the evil Olanzapine, and replaced it with the subtle natural effect of Valerian.
I agreed to take it in small doses for a small time, to see if I like the effects.
With luck I shall soon be discharged.
So.
Doctor's aren't all bad!
This buddhist fellow may have even stood a chance of understanding a small fraction of the subtlety of what I was trying to tell him!
He was even familiar with the works of Swami Vivekananda and J Krishnamurti!
Blessed be the names of the sages!
When the going gets tough.. well lets just say you should see my flying wizard fingers.

As with all neuroleptic drugs, olanzapine can cause the (sometimes) irreversible movement disorder tardive dyskinesia, and the rare, but life-threatening, neuroleptic malignant syndrome. Some also associate all antipsychotics with permanent brain damage.[20]
Other recognised side effects may include:
akathisia; inability to remain still (restlessness)[21]
dry mouth
dizziness
irritability
sedation
insomnia
constipation
urinary retention
orthostatic hypotension
weight gain
increased appetite
runny nose
impaired judgment, thinking, and motor skills
impaired spatial orientation
impaired responses to senses
seizures
trouble swallowing
dental problems and discoloration of teeth
missed periods
problems with keeping body temperature regulated
apathy, lack of emotion
Endocrine side effects have included hyperprolactinemia, hyperglycemia, and diabetes mellitus
Brain Zaps
Auditory Hallucinations[22]
[edit] Metabolic effects
The Food and Drug Administration requires all atypical antipsychotics to include a warning about the risk of developing hyperglycemia and diabetes, both of which are factors in the metabolic syndrome. These effects may be related to the drugs' ability to induce weight gain, although there are some reports of metabolic changes in the absence of weight gain.[citation needed] Studies have indicated that Olanzapine carries a greater risk of causing and exacerbating diabetes than another commonly prescribed atypical antipsychotic, Risperidone. Of all the atypical antipsychotics, olanzapine is one of the most likely to induce weight gain based on various measures.[23][24][25][26] The effect is not dose dependent.[dubious – discuss] Olanzapine may directly affect adipocyte function, promoting fat deposition.[27] There are some case reports of olanzapine-induced diabetic ketoacidosis.[28] Olanzapine may decrease insulin sensitivity.[29] though one 3-week study seems to refute this.[30] It may also increase triglyceride levels.[24]
Recent studies have established :
that Olanzapine and Clozapine disturb the metabolism by making the body take preferentially its energy from fat (instead of privileging carbohydrates). Thus, levels of carbohydrates remaining high, the body would develop insulin resistance (reduction of insulin sensitivity).[31]
that Olanzapine promotes fat accumulation : due to disturbances in fat metabolism, rodents become fatter (but don't have their weight increasing at first). Being fatter, they do less exercise, burning less fat and gaining weight.[32]
Despite weight gain, a large multi-center randomized National Institute of Mental Health study found that olanzapine was better at controlling symptoms because patients were more likely to remain on olanzapine than the other drugs.[33] One small, open-label, non-randomized study suggest that taking olanzapine by orally dissolving tablets may induce less weight gain,[34] but this has not been substantiated in a blinded experimental setting.
[edit] Animal toxicology
In a placebo-compared study of six Macaque monkeys receiving olanzapine between 17 and 27 months, a significant brain volume and weight decreases (8-11%) were detected.[35] In latter studies of the stored samples, the changes were attributed to astrocyte and oligodendrocyte loss,[36] with the neurons spared but positioned more closely compared to the controls.[clarification needed] However according to this study the neurons do not seem to be completely spared. The gray matter shrinking found was 14.6%, but the neuron density increase was only 10.2% which corresponds to approximately a loss of 5% of the neurons.[citation needed]
Olanzapine has demonstrated carcinogenic effects in multiple studies when exposed chronically to female mice and rats, but not male mice and rats. The tumors found were in either the liver or mammary glands of the animals.[37]
[edit] Discontinuation
The British National Formulary recommends a gradual withdrawal when discontinuing anti-psychotic treatment to avoid acute withdrawal syndrome or rapid relapse.[38] Due to compensatory changes at dopamine, serotonin, adrenergic and histamine receptor sites in the central nervous system, withdrawal symptoms can occur during abrupt or over-rapid reduction in dosage. Withdrawal symptoms reported to occur after discontinuation of antipsychotics include nausea, emesis, lightheadedness, diaphoresis, dyskinesia, orthostasis, tachycardia, nervousness, dizziness, headache, excessive non-stop crying, and anxiety. The present evidence suggests that these symptoms affect a small number of susceptible individuals treated with antipsychotics.[39][40] Complicated and long-lasting rebound insomnia symptoms can occur after withdrawing from antipsychotics.[citation needed]
[edit] Overdose
Symptoms of an overdose include tachycardia, agitation, dysarthria, decreased consciousness and coma. Death has been reported after an acute overdose of 450 mg, but also survival after an acute overdose of 1500 mg.[41] There is no known specific antidote for olanzapine overdose, and even physicians are recommended to call a certified poison control center for information on the treatment of such a case.[41] Prescription should be kept in small quantity to reduce risk overdose as acute bipolar disorder and schizophrenic patients can be at a high risk of suicide (Eli Lilly 2010
