As a menopausal or in that transition, my periods are not predictable. So I use my symptoms. If I feel like those things I just mentioned, I'm not sleeping, I'm anxious. My brain isn't as clear as I want it. I'm lethargic. I'm feeling like I want to withdraw from people. And then once I kind of ride that course, I go, okay, now I want to go back into low keto to get my coming here today.
