I’m finding that taking melatonin every night isn’t actually helping me sleep better, although it does make me tired at a reasonable time. But I’m still waking up in the middle of the night and generally being pretty restless. And it hasn’t helped me with my focus or my pain at all, but the working theory was that sleeping better would be what would help with that, and melatonin hasn’t done that.
I think having used it to adjust my sleep schedule was fine, though, and I’ll keep using it for that purpose in the future.
On the plus side, the daylight saving change didn’t mess with me any more than my sleep schedule was already hecked up.
