@SeriousWB: first rule of self treatment is get real stinking drunk... it cripples your judgement and you can´t even hold the knife straigh... but most importanly you feel no pain...
that reminds me about a year ago I met this guy who had this huge ugly scar on his arm... rude as I am I asced how he got it... turnes out he was part of a nazi group as a teen but after finding out hoe stupid that was he got real drunk, put a iron into a fire for a while and bured it out... man that must have hurt in the morning...
