hi i woke up in the middle of the night needing a wee so i got up and went to the toilet by the time i had got to the bathroom my legs had gone wobbly, so i sat down on the toilet to have a wee, and started sweating and my eyes where going blurry, stood back up pulled my trousers up then i woke up layed on the floor not knowing where i was, with a headache, now i feel sick and still have a headache as i hit the back of my head, this is not the first time i have passed out
