This has been my sleeping schedule in the first couple days after senior retreat, as I recover from a fever and other cold symptoms:

Saturday night after retreat: 8-11 PM
Sunday morning: 12:30-8 AM
Sunday afternoon: 2-5 PM
Monday morning: 2:30 AM-12 PM

That’s 23 hours of sleep in my first 40 hours after retreat… well, time for me to get even more sleep!
