On the subject of calories, DON'T stress them, one week out you should be mostly on Protein shakes and purees if your doctor allows it, mine made me stay on fluids for 2 weeks to avoid damage to the pouch. Water is your best friend, and you can flavor it with sugar free drinks, minute maid, kool aid, for sweetener you can add Splenda or Stevia. One thing too that will help you a lot is walking, it helps strengthen those muscles that were manipulated. My surgery was in Feb. and all this is fresh in my mind.
