You could try talking to a nutristionist at the hospital, I had a team that worked in the community and a telephone number I could call office hours, I poured everything I could, down my PEG, if you don't put in the nutrition the body has nothing to heal itself with. The drinks supplied by the NHS can be swollowed as well as being put down the PEG, they are available on presciption, some taste better than others, but they are a complete diet of calories, and vitamins ect... Mail me if you want more info, I'll help if I can.
Sunshine...love and hugs
