Interesting idea re the beer Charm,
I thought I was joking but maybe not ... We have a phrase in Oz that refers to how beer affects one's bowels. It is called the AGB (after grog bog) - this could be a distinct advantage as well as adding calories and improving mood. Although right now, he is a happy little Vegemite (another Oz expression) and is practically bouncing around the place with no treatment scheduled until July 12.
You are right, there is no chance of 3000 calories long term although right now between therapies (chemo and chemo/rad) he is positively gorging! Ok I might be exaggerating slightly

. I reckon a whole 200 calories went down his throat yesterday in single nibbles/slurps/sucks of a dozen different foods but every day things are getting better and we have 3 weeks to improve further. I have high hopes of going over the 60kg (130lbs) mark in the next few days and I can feel meat when I squeeze his leg.
