I think there are people on here who had their first glass of wine on the drive home from the operation.
So the short answer is yes. Things like caffeine and alcohol may irritate the bladder a little. So yes start with one glass and observe if you have any problems, I think you won't and if you do they will probably be easily managed. Then progressively work up until you are on two bottles a night. You have to die of something, make sure it isn't prostate cancer, by over indulging in all the vices.
