Okay, this is getting really bad.
To try and correct my sleeping habits, I decided not to sleep Friday night, and then attempt to sleep at a normal time Saturday night. Only this didn’t work, and I managed to fall asleep at about 4am Sunday morning. But instead of waking up sometime Sunday afternoon, I managed to skip Sunday day all together and wake up at 6:30 pm.
I’m going to buy some more Sake.
