If I've been sober for 5 years now, is it okay to drink in moderation?

ETOH. The majority of alcohol experts would certainly say no. I have been treating alcoholics for over 30 years and my experience tells me this is a very dangerous practice and sooner or later it usually leads to excess you once again. Go to aa meetings for support or consult an addiction specialist to help you with ongoing sobriety. My best.
No. If you are a recovering alcoholic, it is unlikely that you would be able to drink in moderation.
