I had a bath last night (not especially hot) and went to bed. DH came up to bed about 1/2 and hour later and I got up to go to the loo. As I sat down I felt the blood drain from my head and the next thing I knew I woke up on the toilet but lying back against the cistern.
It was really weird, and a bit frightening. I went back to bed and DH gave me some water to drink and I was fine ( a bit shaky) and went to sleep.
I'm not really worried, as I feel fine today, but anyone got any ideas about why?
