Full moon and I'm awake.
It's past one a.m. I'm wide awake. It's often like this around the full moon. I can usually tell the moon cycle just by how insomniac or hypersomniac I am.
It's not a problem. I flow with it these days. It's just like living with the changing tides. I adjust the particulars of my daily life to align with the fluctuations in energy. Decades of living with chronic fatigue have taught me that!
