Just that really.
It's quite a few years ago now, but the last thing I recall is struggling to get off the bed to go home and a nurse saying 'we're just giving you something to relax you'.
I woke up out of the induced coma 2 weeks later (and had no idea that I had been in one - in fact I thought I was still waiting on a doctor to see me so wanted to go home as I had been waiting too long - another story lol). During the coma my organs had started to fail etc. and I almost died. I realise I needed to be in a coma as I recall they couldn't get my BP above 60/40 and they were fussing around me and what happened while I was in the coma would indicate that I damned well needed to be in one.
My only question is, is whether you're ever told that we're going to be putting you into a coma?
