The irony is most "mind influencing" medications do poorly when compared to placebo's (sugar pills) positive thinking means more than anything. No matter how much you have to force yourself to think positive its going to do more for you than any pill...

And, as nullific pointed out the majority are inherently dangerous and not even proven helpful but that doesnt bother the FDA no sirree.....And, dont get me started on doctors who prescribe things that companies give them for free.....Here's a good clue if your doctor(any type) actually cares about his patients. He'll have up to date studies littered around his office. He/she will also double check and recheck findings or diagnosis on the suspicion he or she might be wrong . I've only found one doctor so far that meets this criteria but im sure there is plenty out there. Good luck.
