It seems to me that the whole psychiatric model of therapy is dictated by the drug manufacturers. Doctors get their information on the drugs from the drug salespeople, who more or less bribe the doctors to prescribe their drug with attractive paybacks for even attending an 'information session'. The information on the effectiveness of the drug is entirely speculative, and has no long-term proof of it's effectiveness. So called side effects are brushed aside, when in truth, these are the effects of the drug, inclusive are the bad things.
I have heard that new anti-depressant research is on hold, maybe they know full well they do not work. There are other far safer and less addictive therapies that work just as well.
