I know many will have different opinions than mine. I was in mexico for my surgery. And the night before I had ONE margarita - and a weak one at that.. Kind of a farewell party to my old life. The alcohol will be long gone out of your system by surgery time. A huge concern for us having surgery is that we will give up our addiction to food and pick up another - alcohol.
I say, have a couple, enjoy them. Because you will have to limit them (or give them up) after surgery.
