I just started on 10 mgs of Citalopram (the generic of Celexa) on Monday. My doc said drinking every now and then was fine. I told her that I usually get drunk 2 or 3 times a month and she said that that shouldn't be a problem as long as I'm not drinking every day. Talk to your doc about it, but I did drink quite a bit last night (Halloween and all...) and I feel fine today. I'm sure that light drinking would be perfectly fine.
