Thank you Sarai
I have been looking into causes for blackouts too, they are quite interesting, yet completely terrifying! My other half still states he won't drink in the house, this I will believe when I see it. He is a heavier drinker than me but thinks that because he is a 'happy' drunk, sees no reason to stop. I know after a week of not drinking at home he will go out and buy wine so that I will have a drink with him.
This can't happen though as I will not let this happen again, had I have been in a bar god knows what would have happened to me, it is lucky I was at my friends.
