For people who had FSWL docs
Only the day before surgery. I had to lose 15 lbs before I could have the surgery. They weigh you the morning of and will turn you away if you haven't done your work. This was so much better than having to do a pre-op liquid diet, But afterwards you will have two weeks of full liquids, two weeks of puree and then onto real food. I had my surgery in March of this year. So I wouldn't think much has changed.
