Hi MB12,
Welcome to the forum and congrats on your pending WLS. Advice from me is to follow the presurgery diet to a T. I realize this is difficult, I had two weeks of liquids only and a week before that of only one meal a day. What got me through it and every issue I've faced since, is remembering my primary reason for doing this. Yes it's about getting healthy, but why? For me it is a 5 year old grandson, that I can't play with for more than 5 minutes without being out of breath. I picture him every time I felt like eating during my presurgery diet. Helps a lot. Also anytime you're feeling stressed, confused or have questions, come on the board here and read what others are going through and/or post your questions or feelings. We're here for you with advise and a virtual hug if you need it.
