Wow. I am real sorry to hear about her discomfort. I have been using a PEG tube for 3.5 years. I started with jevity 1.5 but have moved to a nutritionist. She does custom formulas of real foods and supplements to keep me going. She bases her programs off of blood work. My recommendation is to find a Nutritionist. I have found them to be the best at food management, far better than any of my doctors. Best of luck to your mom.
