My husband went through 35 radiation treatments and 5 chemo for Tonsil cancer. His pets can shows cancer is gone but it's been 20 weeks since last treatment and he is still using the feeding tube. He is eating some foods but salty foods and citrus foods or drinks bother him. He can only take small bites. He'd like to find something to fill him up so he can get rid of the feeding tube. Any suggestions ?
