Vernon... is your not able to swallow related to pain? If so try using the magic mouthwash to numb then sip water, or something (ensure) 5 feeds a day is great. If you want to try running a couple overnight on a slow drip then it may take away being hooked up every few hours during the day and give you more freedom. (you could probably fit it about 4-5 cans in one bag and just let it run very slowly)

You should continue to try and swallow even just a little fluid. I get that it's painful but suck it up and do even a little - radiation burns the crap out of your throat etc... you do not want the muscles in your neck to atrophy and to be stuck on a peg for life. This can happen. So it is important to maintain the swallowing reflex.. Hugs and keep on pushing through. The end will come soon enough.
