Not a doctor here but many of us have a big letdown post Tx leading some to a state of depression but probably affecting all as we feel the affects of being "abandoned and cut off" from our daily doctor visits. We are told that we FINISHED Tx but we feel horrible and we also wonder what next, am I cancer free; what about recurrence, etc, etc. Our mental activity can cause a lot of adverse affects during and post Tx so his inability to sleep may well be attributed to his mind working in overtime behind the scenes so to speak. I have always maintained that the mental part of this cancer is 50% of our battle yet even at CCC's almost all of their attention is focused on the actual killing part and it's physical side effects. IMO all CCC's would do everyone a huge favor if they added a physiologist to the active part of their team and made us see them at the very beginning, at the very end and maybe a few times in between and afterwards.
