I was prescribed Paxil due to a misdiagnosis. Wow, that was awful. Whatever positive things it was supposed to do never happened, but if you wanted your sex drive destroyed and to have every sleeping moment be the most vivid dreams it did that for me. Of course, all of the dreams were directed by Steven King and I woke up screaming in a cold sweat but they were vivid. And if I could get back to sleep I'd have another just as bad on a new topic (they didn't repeat). I watched a friend be driven into paranoia by SSRIs. As the affects of the drug ripped her life apart, her doctor kept increasing her dose to 'fix it'. When last I heard from her, she'd lost her license, been fired and lost most of her friends -- an addicts journey except that she was following her doctors instructions.
It's interesting to me to see that some people have really been helped. That suggests that doctors need much narrower guidelines for prescribing these drugs.
