I gave myself monthly goals to start small. Quitting caffeine (since that will have to happen for at least a while post op), using a smaller plate when I eat, not drinking with meals, and making sure I had all the over the counter meds I might need. The mental commitment is very personal, so it’s difficult to say how to prepare for that. I looked at why I was having the surgery, what types of realistic goals I wanted, how I’d deal with stalls, how I’d deal with people asking me questions, how I’d deal with food mourning, things like that.
