Hi Minnow,

There's nothing magical about the amount of time that passes after treatment before a body starts to feel better. Part of the process of recovery is the body rebuilding itself - and this takes nourishment! My fear is that your friend is prolonging the recovery process by denying himself the nutrition that he needs.

Can he swallow well enough to down a few cans of liquid nourishment (Boost, etc.) per day? If he could get 6-8 cans into his system, his recuperation would likely accelerate.
Best, Sheldon
