I first did it five years ago following a bad day. I had been put on seroxat to treat the depression i was going through and was scaring myself to death from my suicidal feelings. I now know that those feelings were probably a temporary side effect of the medication i was on, which puts you into a state of emotional turmoil in the first few months! Funny that being an antidepressant but there you go.

That was it till february of this year, and now i cant stop thinking about it! Im not going to try to summarise everything thats been said in this forum, because the reasons people do it are quite diverse, and i would make a bad job of it, but this is a good place to sit and read some of SIers experiences. I hope you learn something from it.
