1-2pm is for ???

I left myself a cryptic note for trying some lifestyle habit a few weeks ago, and can no longer recall its meaning. Here’s the note in its entirety:

> 1-2pm

Any suggestions for what’s best done at 1-2pm? I feel like (70%) it has something to do with diet or exercise (but not napping). I’m half hoping to hear a more useful idea than the one I forgot, which wasn’t spectacular enough for me to remember. I already searched web, mail, and my RSS.
