Can you tell if it will be a good day?

Sometimes I know right when I wake up. Ok twice. The only way to describe it is I feel like my blood pressure is stronger, I’m already pretty well hydrated before drinking anything. Nausea and dizziness much less noticeable. Then I wait all day for the other shoe to drop cause POTS is a sneaky beast. Once my son said “mom you have energy today!” I wanted to cry cause I knew it was so rare. Is this familiar?
