I am pre-surgery, but I have fears like yours too about what happens after surgery. Hey, you recognize how you are messing up and you know that you need to turn it around so you are already on the right track! So you have been off the wagon for a week and a half. Not a huge deal if you turn it around now. It takes a while to create those healthy habits so don't beat yourself up too badly! Keep the praying up too, it works. You have lost 72 lbs and are living an active lifestyle, that is great!
