Hi Jer-Z Girl,
It will get better by the 3rd day. Hold On! I've switched over to the Bariatric Advantage Protein shakes and I must say they are MUCH better than the Premier Protein Shakes I got from costco. When I say 'Better', I mean in keeping me satisfied. I made the Bariatric Advantage shakes with my Magic Bullet and the portable shaker and they were great either way. I have a shake or Bariatric Advantage pre-packaged snack every 2-3 hrs along with plenty of Water, and I am good. My surgeon recommended 80oz of water per day, but I'm targeting 96 oz (3 32oz bottles) per day.
Hang in there - You can do it!
