I can’t learn this pattern

Some mornings when my alarm goes off, I find it impossible to get out of bed. This shouldn’t happen. As part of my strict migraine prevention routine, I go to bed at the same, social-life-killing time every night. But the fatigue is so overwhelming that I turn my alarm off, roll over, and go back to sleep for several hours. I then berate myself through most of breakfast about how lazy I am. Then, somewhere between polishing off the toast and finishing my (decaf) coffee, the first wave of pain hits.

I’m not tired those mornings because I’m lazy. I’m tired because fatigue is a premonitory symptom of migraine. This happens at least once a month and every time I’m surprised.
