Never knew what happened in between and how long I was out cold either.
I know how weird it is waking up from that, especially not knowing how long you have been out for (but I know it was a minimum of five minutes, but could have been anything up to half an hour really).
The next day I could not breath. All the tissues in my neck were swollen. My GP did jackshit. I don't think I had much in the way of bruises either, except some very pale ones a few days later.
I do remember my last words to myself, after unsuccessfully struggling to get out of it "oh well, looks like this is it, I am going to die", then blackout. I should really think up better words for next time I think I am about to die, those ones, kinda suck.
