Glenn, I remember the times you called me while I was in the hospital. Trust me, you really don't feel like eating, and yes part of it is being scared, cuz your dad & I had simmilar reactions with that first big meal. When his body is truely on the mend,it will tell him to have an appetite. I lost over 20 pounds during my ordeal. So quickly, I was told I looked like someone had beaten me up and given me black eyes. I know you're aware, but it's really good your Dad does have all that reserved energy for his body to thrive on while he's going through this. If he had been very thin to begin with, it would really be more of an issue then.
