24 hours before the surgery and I gained weight

This surgery is only a tool to help you lose the weight. But you are the one who has got to do the work. When you cheat, you are only cheating yourself and you will only make yourself feel worse. You can do this, but you have to really want it. Your future depends on it. I am 6 days post-op and happier than I have been in years and lost 7lbs 4 oz this week alone. You can do it. Don't give up, just make up your mind to listen to your heart and what you want is a healthier, happier future. Go for it.

Thanks for the encouragement, I really needed it.
