My husband has one. I have never used it and now I dont want to or need to. He had to have it and was deterined to quit. He used it for about a month when he wanted a smoke, and now he is back on regular cigs and has been for 2 yrs. I don't think it is all it is cut outto be, plus expensive.---KathyofAlabama u can do this. Just think you are having the surgery to turn your life around for the best and for your health, y hurt it with a cig. Once u can get through the 1st 3-4 days it is much easier (I've done it b4). You can and will do it. Best of luck.
