I would shoot for drinking as much water as he can tolerate. That will help to flush out his organs. He may need a med. to help with his symptoms. Many people drink to self medicate for depression or anxiety. Just try to keep focusing on u and keep yourself centered. Relapse is common, my husband got to 4 weeks, than 6 weeks only to go back to it. I hope for u both that this is it for him. The Dr. is your best bet to help him get through this. Take care of U and remember one day at a time.
