Something I hadn't thought of trying before: black out curtains. I live in a studio apartment and have two windows. So, I bought some inexpensive black out curtains and covered my windows. The lack of light, has literally been a life saver for my body clock.

The pandemic doesn't help but when I use the black out curtains, I conk out and wake up around 7:30 a.m. without my cellphone alarm. I'm so grateful.
