I am 10 days post op and I crave (at times) chewing. So I will grab some Jello and make sure that I chew it. I know I am not hungry for food, I think I am starting to miss the idea of food (if that makes sense). When I am busy, walking, working around the house (small projects), I totally forget this "craving" and sometimes I also forget to drink my fluids as well. Not sure if my insight on myself helps.
Good Luck and Congrats on making the change!
