Funnily enough, I’m going through chemo, am house-bound with nearly zero activity ... and that’s about how I’m (naturally) treating sleep right now myself. I’m more like 40 than 77, but when my body says it’s time to shut down ... it’s nap time, and they’re glorious.
For chemo, I just take one pill a day. It’s like a sleeping pill. I take it at night, but feel drowsy all the time. It’s called fatigue.
