Thanks for your question. Patients should stop drinking alcohol a week or two before the surgery. Best person to advice you will be your specific surgeon. You definitely have to choose your surgeon correctly and make sure that he/she has the training and experience to meet your goals with absolute safety. A key quality indicator is Board Certification by the American Board of Plastic Surgery. Don’t settle for less than a Board Certified Plastic Surgeon with specialized expertise in this procedure.
Your surgeon has very specific protocols for this. In my own practice I don't really care if the patient has a drink the night before the operation.
