I had this experience when I first went in to see surgeon..vice versa. I told my doctor I wanted to do Bypass but when he found out I was a smoker he said he would not perform the surgery . Reason being was because if you smoke when you have bypass you get ulcers. So basically you are in pain all the time. So i decided to do Sleeve. I will tell you that it was the best decision I have ever made. It was non painful except for the gas pain you will have for maybe 2 weeks..I have lost over 60 lbs and I am 4 months post op. I feel better then I ever have. But you have to go with your gut intincts. My doctor was highly recommended and If he told me what was best then I listened to him! Good luck and relax! Everything will be ok!!
