Congratulations. I had my sleeve on 11/12. I'm excited that I move to what my surgeon calls Stage 3 on Christmas Day. I get to have pureed peaches, green beans, cooked carrots. Basically, if I can pour it, I can drink it.
I know what you mean about getting enough protein. I had a lot of problem with not liking the taste. I finally just mix the vanilla with a little chocolate and I can get it down. I take a 8-10 oz. bottle with me on the way to work and drink that while I'm driving. I have another bottle with freezer packs that is about 15 oz. I drink most of that for lunch and leave about 5 oz which I drink on the way home from work. It works for me. Weekends are harder because that is not a routine.
I hope you reach your goal. Goals are important but don't stress if it is not reached by your expectations. That can be bad. It will happen.
Happy holidays.
