PP, I know lots of people who can go 30 days without a drink. Including me. About half my friends. (rough estimate). A lot of people just don't drink. I think for a lot of people its just a non-issue.
Also I am wondering. H drinks every day. Since about 2 months pre-BD he went from drinking maybe 2x per week to daily. At what point do you say someone has an addiction? I believe he is self medicating for the depression, but what is the risk of becoming an alcoholic?
