Thanks for all your replies. It means so much. Had a good cry to my husband and told him we can't go on like this. He agrees and suggests we do this together one day at a time. He suggested that we join the local gym, so it'll give us an option at the weekend rather than our usual pub visits.
I think he was quite shocked I was so upset, but I can't tell you how ashamed I feel. Alcohol has caused so many problems in my life and I don't want to be ruled by it anymore.
