Tangential thought: maybe the two are related? Like, on days where you're super busy, you're more likely to get a bit dehydrated from the busyness (lol, root of business?), and ALSO more likely to miss steps in the evening routine, like bringing the water bottle to bed, for the same reason.

I'm thinking it's like survivorship bias, but for memory. Nobody remembers small wake-ups, say to drink some water, but they're definitely gonna remember if they have to get up to get the water because their bottle is empty.
