Chuck,
Welcome.
I believe that the keyword is patience. It took me a long time to get back my stamina. I was so skinny that I thought that I would never be able to wear my old clothes again, and now they are getting tight! I recently had to change from Boost Plus to regular Boost for fewer calories, and guess that now I will have to make smaller chocolate milkshakes! I don't want to gain anymore weight! It is great that you are back at work so soon...just don't overdo it. It sounds like you are doing well.

Take care,
Danny G.
