Migraines and ME/CFS - Discussion on how they may be related

[Tom Hill]

Lack of sleep is a trigger for migraine, but for me that takes a few consecutive late nights, not just one without any other stresses.

This pattern of accumulated triggers (what I call a hop, skip, jump effect), as well as the remarks of others about how they kept getting the triggers wrong because they didn’t realize the onset process was delayed, mirrors the general pattern of PEM triggering, I think.
