If you smoke or use any form of nicotine, stop now. Eat well-balanced meals and drink at least 32 ounces of water a day. Get plenty of sleep and exercise and consider taking a multi-vitamin supplement. Three weeks before surgery, stop all vitamin E, aspirin, ibuprofen and other over-the-counter blood thinners. You may continue taking Tylenol. (If you are taking Coumadin or other prescription medications, do not stop your medication without consulting with your physician). Many herbal supplements such as Gingko, Ginseng and Garlic also promote bleeding and may interfere with anesthesia. Please inquire for more detailed information.
