Frank,
I know this is a rotten journey but the fact that you are able to complain about it is good. Everyone here has complained about something at some time during their treatment and recovery. With every complaint someone has learned something. Don't worry about being upbeat, when you vent I would suggest that something positive will come from it.
I suffer from sleep apnea and use a CPAP machine. My wife used to complain about my restless loud sleeping. Now she wakes me to make sure I'm still alive. You are blessed to have a partner that looks out for you at all times. Talk to your doctors and mention your wife's concerns about your sleep. I'm sure you will find a solution.
Cheers,
Mike
