My biggest issue after sleeve surgery was my increased sense of smell. I could smell food heating in the microwave from upstairs. Nausea Meds were my salvation. As far as cravings I had success with diet frozen fruit pops. You may want to try those.
I began 2014 at 409 pounds. June 11th I was sleeved at 377. Today I am 282. Keep true to high protein and stay under 10 grams of sugar and you will be fine. There Will Be Plateau Moments though.
