Doctors' opinions vary on alcohol post treatment. My ENT/surgeon says it's better not to drink at all. My RO says a glass of wine or beer a day is fine, just no hard liquor based on his patients's experience (he had noticed a definite link to hard liquor and reoccurence but then saw reoccurence where they had totally abstained from alcohol) . Both agree that if it bothers my mouth even a little, don't drink. I worry about the reports linking alcohol in Mouthwash to oral cancer. Yet I still have a beer or wine for special occasions and certainly plan to toast the Holidays. Just my choice - not a recommendation for others. I certainly am no longer a social drinker.
