My husband has been drinking for approx 20 years. Only drinks beer, but about a 12 pack a day. He has a couple before work, doesn't drink at work, then starts again when he gets home early in the evening until he goes to bed. The court ordered him on home electronic monitoring and no drugs or alcohol for 30 days, so he has to quit cold turkey. What can I expect and how do I know if he needs medical attention or if this is something he can go through at home?
