I tried an experiment on Wednesday. I took my meds at the regular time, except for the Seroquel. I waited to take that until just before bed. I didn't have the gnawing need to nibble on food all evening. Yesterday, in contrast, I took all of my medication and nibbled all evening. I'm going to try taking the Seroquel later, like just before I'm ready to go to sleep.
The trade-off is that I don't just fall asleep automatically, so I'll have to plan to go to bed at a certain time. Staying up too late is another problem entirely.
I guess committing to write during Advent is turning out to be a pretty great idea so far. More tomorrow.
