I Had A Shunt Operation In February And Have Not

I had a shunt operation in February and have not had any alcohol since then. I have fully recovered from my injury and am back at work. My doctor told me that I can have no more than two drinks. He is afraid that I may have too much to drink and have a fall and hit my head.
I don't plan on drinking to get a buzz. Just a drink or two on occasion. What do you think?
