Too spammy, didn't click? Here's the kicker: "substantial exercise the previous day, sleeping longer and later into the morning, and eating a breakfast high in complex carbohydrates, with limited sugar"
But how else is my late-night bedtime procrastination cycle going to continue? I just absolutely _must_ stay up until 2:00 AM reading Wikipedia pages on obscure tropical plants, because I guess I only need to be up by 8:15 AM for my 8:30 AM standup!
I'm only a data point but my experience is very different: I never had problems waking up and being immediately functional, with or without breakfast. Maybe that counts as "limited sugar"?
