You know, he could be feeling really a lot worse than he even lets on. My H will let himself get really good and sick before he will say so, or it's usually because I see it.
Maybe you could suggest he ask his dr. about the testosterone while he is there, that it couldn't hurt to ask. My H has told me some embarrassing things he and his dr, talk about, and he made me blush. I think fixing his sleep problem, and any other physical problems will go a long way towards making him feel more lively. How long has it been since he has had a complete head to toe physical?
I don't know what to do for my mother for Mother's day, she won't go anywhere, because she is taking care of my stepfather who had a stroke last year. Usually it's flowers or a fruit or gift basket, maybe the same this year. She loves lotions, so maybe stuff like that in a pretty basket. Usually I don't go to MIL's for Mother's day, but maybe I should this yr? But H might get his suspicions up, so I don't know.
