Doc has said that it's most likely just a sever lack of sleep that's caused/causing them. Given the night it happened the worst (the one that prompted the post) I was going almost 48 hours on about 3 hours sleep, it's "not surprising to have effects".

Spring Angel I've had a few nights in the past week where I've woken up practically dripping in sweat too. One time in particular I remember waking and the bottom sheet, pillow case and doona cover were all damp. I had read prior that b/fing can result in being hotter - but that was crazy!

*Linda* - I think I'm awake when it's happening, not 100% sure though. I'll be asleep, and then it's like that thought that she is caught in the doona covers is what wakes me... or I wake and it happens a millisecond afterwards.
