Totally experienced the same thing. Basically, get your protein and water, and enjoy the time (and the weight loss) . . . speaking for me, it passed and I'm now quite able to feel hungry again. Thank goodness my sleeve is still restricting how much I can eat and I'm still trying to make the right choices--protein, protein, protein!
I'm seven months post-op. Today, for example, I had a spinach and cheese one-egg omelet for breakfast--with an English muffin, as I'm not quite as carb-free as I should be. Had cottage cheese with pineapple and blueberries for lunch and a shrimp stir-fry for dinner. For snacks, I've been taking advantage of Medifast things a friend has given me--a package of pretzels and a peanut crunch bar today, each with about 110 calories and 11 grams of protein . . . I also tend to snack on cashews quite often. It's not like the old days! but that's a good thing.
