THIS IS A REALLY INTERESTING LINK BY THE WAY

i have heard of that drug doing wonder for SI (so weird calling it SI, ive always said and been a cutter i never knew how many people do this, it was always a hush hush growing up and you got sent away if anyone found out)

anyways works wonders, poss the link might help explain why and you might already know some stuff in there, it's also a good link to print out and give to fam or friends if they ever question why or don't understand SI

so to yuor original question. never used it, but there is plenty of reviews about it if you google.
you do need to watch your liver levels on this drug though i'm sure the doctor will keep up with that.
