My question is this.... 2 times on birthday party dinners i had food, and a couple drinks. I was very competent, and i was not drunk because i don't like to be or get drunk. But I leave the dinner party feeling very well coherent and know what i'm doing. But after a while my stomach starts to hurt, and then i feel light headed and then I faint. I am very bothered and puzzled about this because i have never had this problem, where i eat and drink a little and pass out and collapse. It happened last night 1/08/2011, and in the beginning of October and very end of September of 2010. I used to drink more than this and never passed out, so you can understand my reasons to be puzzled. Can you tell me what it might be?
