Hi, i am pretty new to this, but I will try to answer your questions. I had my surgery on August 18th. Was sore for about four days, had to sleep on back, not on sides. By the 3rd night i finally made it to my side and got a good nights sleep. LOL!! I did not take any pain meds, but I do have a pretty high tolerance. Went back to work on the 5th day, even though they told me I could take a week or two. I can still see my marks from surgery but every day they are getting smaller, and harder to see. Now - the weight loss - this is different for EVERYONE. I have lost 14 pounds so far.
