Hi John, I'm sorry I can't answer your questions, but I do have a suggestion.
What about when going out with friends you drink a non alcoholic drink.
My hubby was alcohol dependent and has not drank now for 14 mths. When we have had to go to social occasions my hubby will drink non alcohol larger. You will have to check the labels though as some say they have no alcohol content when some do have a small amount.
Hope this is of some help.
Regards
