I too was sleeved on 12/14 and I am on the purée stage. I drink 2 protein shakes a day plus some purée foods like soup, yogurt, oatmeal, etc. I too feel hungry about every 2 hours. I asked my doctor about this and she said that was normal and when I feel hungry to eat or drink something. I also worry that I am taking in too much so I'm going to start to measure my purée in a 4 oz cup so i don't eat more than I'm supposed to. Try staying full on water and protein shakes so that your stomach doesn't feel empty.
