Maybe instead of worrying about completely giving up, try setting a reachable goal, like quitting for 30 days. Don't drink for 1 month and see how you feel. If you want an explanation, go to the dr. and tell him how you feel about your recent drinking and especially what your wife said about your marriage. The Dr. will likely tell you if drinking is becoming a problem, to quit or cut back for a while. Voila. You now have an excuse for your friends: doctor's orders.
