I guess my brief question prompted a number of concerns. I have consulted with my doctor and although he did not advise me to stop drinking (moderately), he did say it would be a good idea.
My question was really meant to address whether there would be any impact if a moderate drinker stopped drinking a week before the operation versus, say three days. Probably a period of time that would not make a significant difference.
Other family members experience was that stopping even three weeks in advance did eliminate the fact that they required additional pain killers, anesthesia versus the norm.
Anyway, thanks for all the suggestions and concerns.
