I drank about 3-4 months post op. BUT PLEASE, DRINK SLOWLY. and try low alcohol items first, like a glass of wine or a wine cooler or let a beer go flat. I learned the hard way, and when your body weight goes down plus with this surgery, you get drunk faster and it takes less to get you there. I find that liquids go right through me, so there's nothing to throw up when you get way too drunk. Just take it easy!
