I am worried about taking supplements because I tried taking 5 HTP for a little bit. After about half a bottle was gone (take 1 pill day as often as I could remember) my depression wasn't any better, I felt more hopeless than ever, & I was having serious rage issues. My anger got so bad one day, over nothing, that I wanted to go & get in a fight. I either wanted to beat the crap out of someone or get the crap beaten out of me. I didn't care which one. Another time it got so bad I seriously wanted to to OD one some medicine I had so it would kill me. Since I stopped taking it my anger is much better now. It is for those reasons I am leery of taking an OTC suppliment. I really don't want to go back to that state of mind again. I am truly worried about what would happen if I go back there again. Would I survive it? How bad would I get messed up?
