It's weird because I wasn't really convinced that the shedding was a thing and migraines I get aren't something predictable (the only reason I don't use that as an excuse for bonus sick days is that karma would have me get a real migraine the next day).

But because it's not predictable, it's harder to say with any certainty if that's what is going on, but I know that it's been every couple of weeks I either wake up as though I had slept through a migraine, or feeling light-sensitive, or nauseous.

I wish that there was more certainty than the anecdote I can add, but instead it's just this strangeness and the suspicion that this might be the cause.
