Just a quick deviation from your emails to him. Someone may have suggested it already, haven't read whole thread.

With all the bicycling you're probably gaining muscle mass & loosing inches. You also mentioned your appetite isn't so good.
Have you measured chest, waist, hips to check this? Are your clothes more loose?
You're doing so good with meds, sleep & taking up for yourself!!

Now, keep us informed on how this friendship (?) works out.
