Michelle,
I had a very similar diagnosis as your husband, Stage IV base of tongue with 3 neck nodes. The PEG was my best friend. Once I felt better I would hang it on a nail on the wall by my desk at work and feed while I used the computer. I also was able to play golf and exercise some while wearing it. I am a big proponent of the PEG and would not have been able to make it without the PEG. I got a prescription for the Yankauer machine and kept it by the bed at night and by the easy chair by day. It was a big help.
Please tell your husband that there is light at the end of the tunnel. I feel great and am doing very well now.
Best of luck,
Danny G.
