A few thoughts one all this...
First off, outin's comments are just about spot on. They make very good sense.
Second, there is no one size fits all -- especially when it comes to psychoactive chemicals (and that includes everything from over the counter sleep medicines to prescription drugs to magic mushrooms, including tranqs, uppers, downers, hash, booze, nicotine, etc. etc. Although some broad generalizations can be made, individuals vary over an incredibly wide spectrum on their reactions to and potential need for any of these compounds.
Thus no one responsible -- no one -- should say to someone else that something worked or didn't work for me, therefore it will or won't work for you.
Third, if one has been prescribed a psychoactive medication for some mental condition, one should not change it (or, particularly, drop it) without equally competent advice to do so, and under some competent supervision (which does not include your room mate, significant other, or the guru down the street). Why? Because many of the conditions for which these medications are prescribed can and do vary with time, and while one may feel just fine dropping the stuff, one may be letting one's self in for a serious relapse.
On balance, I think that western people are, perhaps, over-medicated -- but possibly not by that much -- with regard to psychoactive medications. A good deal of that over-medication is patient mediated, however; it is remarkably difficult for a doctor to say no to a patient who is screaming that such and such a compound is just the thing (perhaps even more of a problem when it is the parent of the patient). (by the way -- this is even more true about such things as antibiotics, but we aren't talking about that here).
And just as a bit of cred here, as a minister (of music, but a minister none the less) I have been involved in quite a number of interventions or rescues involving more different psychoactive compounds than I can possibly remember. Some tragic.
Be careful...
