I would say get in some physical activity before surgery - will help with muscle memory, also will be easier to bounce back to your routine once you are cleared post op. I would stock your fridge and freezer with good post op choices so you don't have to cook. Check out the blog The World According To Eggface, and Bariatric Eating for some tips and recipes. Also try practicing not drinking 30 mins before and after eating - it is definitely not easy to acclimate to at first (my gastric bypass was 4/18 and I still have to remind myself). If you drink alcohol or soda/carbonated drinks start eliminating them now so you won't miss them as much post op.

Lots of good luck with your surgery!

I second that! Good luck! Let us know how you're doing when you get a chance!
