Update: My Dad has decided to get a feeding tube. He can barely get water down, which by reading your posts I had told him this might happen. He is just one of those who doesn't want to just "take your word. ". He had to try without a tube, just to see if he can make it.

Anyways, he knows now he needs a tube to get adequate nutrition and hydration. Did any of you have one put in this far into treatments? He is a little over halfway through. Treatment is scheduled to be done April 25, unless this feeding tube procedure makes that date later.
