After I eat carbs or sugar (candy, pizza), if I stay seated (class, meeting) I have a tendency to fall asleep. I have also fallen asleep while driving once (after eating a bag of gummy sharks). I fall asleep during lab meeting (after eating 2 slices of pizza), and I was sleeping in class last night (after eating a starburst). It's been a weird problem for a while, and I'm not sure what it's from. Internet searches really haven't helped. If I move around after eating carbs (walking, standing, etc), I'm fine.
Anyone else have this problem? I'm not diabetic, but I am on Metformin. My 'passing out' started well before the medication, though.
