I don't know what the answer is, but I know recovery is painfully slow. I'm just over 2 months out from radiation. Still not eating solid food, living on Ensure (barf!) and some weight gain stuff I got at the health food store. Nutrition & calories are important. I'm able to (barely) hold my weight with +-1600 calories per day. If I get less, I feel much worse. Energy level is very low, and depression is a real problem.

I actually ate an ice cream bar yesterday, almost the whole thing. I'm considering that a turning point and will look for improvement every day even if barely perceptible.

What I'm getting from those who've gone before me is that recovery takes a looonnng time, and I need to be patient.
