I know what your going through w/burping and gurgleing...it is embarassing. I can only take about 4 sips at a time and the colder the better, for me. My doctor told me not to eat lettuce, it is hard to digest and fills your pouch too quickly, so I have not had any lettuce. It is best to eat your 4oz of protein first, then if your still hungry, eat your veggies. Also if you eat too late in the day (my rule is not to eat after 7:00 pm) you will be sick whenever you lay down. I'm still learning as I go and it will be 1yr on june 1st, 2008. I have lost 55lbs and I feel great.
