I had two attempts and thanks to SS I know why they failed so next time I won't fail again ! I tried to ctb way before the days of internet, when it was nearly impossible to get any decent info on methods. First I tried to OD on Diazepam (now of course I know that's impossible) and since that failed three weeks later I tried hanging (partial, no stable anchorpoint high enough in my flat at the time). Managed to lose consciousness, but then my body started thrashing around until I ripped the door off the hinges...at the time I was totally confused as to what had happenned, only ever since I read here on SS about convulsions after losing consciousness due to hypoxia that it all started making sense to me !
