that's possible. He was so glad to not have all the pain in his face which has kept him from sleeping for a couple of months now. But today...it's 9:30 and he hasn't even gotten up to take his dog out yet. I think the tiredness of the chemo and/or Keytruda has kicked in. He went from an 11 in energy on Tuesday and started really slowing down yesterday and seems to be out of it today.
