AH, I wasn't aware that they could pass through stages and get to a point where a little bit could make them seem drunk. This could explain what is up with the behavior the last few days. Is there somewhere I could read about this?
You might want to check out the local Alanon meetings. They are free and in most towns. They are set up for family and spouses of alcoholics. You can just sit and listen. It takes going a few times to get used to it, but it really helps. It is a lot of the same stuff you hear on this site, but also deals with what drinking does to people.
