Pro tip: I moved my nap from 3pm to 1:30pm and the after-feeling changed in a week
I used to crash at 3pm and wake up groggy for the rest of the day, but last week I tried pushing it earlier to 1:30pm right after a light lunch. By day 5 the difference was obvious, I woke up clear headed instead of foggy and it took me about 10 minutes less to shake it off. My wife noticed too and said I stopped being grumpy at dinner. Has anyone else found that the time of day matters more than the length of the nap?
