Hi everyone! I too am having trouble with feeling full & bloated w/Novaris Isosource 1.5 Cal, 375 calories/can. For now I am eating orally, soups, yogurt, softer meats, milk shakes, etc. My chemo/rad starts 4/5/04 & I know I'll have to find a formula that works. The dietician says 7-8 cans a day. I'm 6'1", started this journey at 225lbs, down to 195. Trying to put some weight back on now. The dietician seems puzzled about bloating & fullness w/isosource. Good to know others are having trouble & we can share solutions. I even tried mixing isosource in a big milkshake w/banana, stawberry icecream, but still experienced the same fullness.
