I stayed on 20, but it wasn’t always easy. I will admit to struggling mightily at times. Legs zinging at night, muscle cramps, and fatigue are all real. I was blessed to have a job where at least some of the time I could adjust my duties by working from home or other types of schedule adjustments, when things were at the worst. Like you, I found cycles, most of the time I could manage, but there would be times when things were harder.
I had hot flashes that would start almost like a seizure, where my brain kind of glassed over, I still occasionally have these, but much less often.
Have you identified ways that you can adjust around some of the troughs?
