> a cycle of vomiting and sleeping for a period of 72 hours I've been in such cycles, though mine usually last for about 6 to 12 hours only. That's long enough. I always figured the stress of my migraine caused my body to say, "okay, get all the food out, we shouldn't be digesting anything at a time like this". I've vomited 20 to 30 times in a night before. And the weird part is, I actually have good memories of these times. The exhaustion and sleep that follow are amazing, and I feel especially good the next day. I've read sometimes migraines have a serotonin effect, maybe there's some chemical reason my brain decides in retrospect that it was a good experience. I recently saw a Veritasium video about how the ending of an experience shapes our memory of it [0], maybe the relief of the migraine finally subsiding is a good ending and shapes my memory of it.
