Hi, Keith
my husband was mainly frustrated 2 weeks out of therapy that he was not bouncing back faster - although he really was very lucky to recover as quickly as he did.
On the pychological component of eating - yes, that was a factor for him. If you think about it, you have been undergoing operant conditioning to NOT eat for the last several week. Not quite zapping the lab rat everytime it goes for a food pellet, but close.

I am glad to see that your sense of humour has returned. As you try to build your physical stamina back up, please remember that its ok to push yourself a little - but that you HAVE TO REST and recuperate between exertions.
Very best wishes to you from across the pond!
Maria
