Sorry you have to sleep so much Sally.
I used to live in a humid city down south. Sucked the energy right out of me. While I still have fatigue issues, they tend to be worse only when I am having other symptoms.
Changing my meds knocks me for a loop. If I were 20 years younger it wouldn't matter, but being older means I don't bounce back quite like I used to.
Hope this resolves for you soon.
