Just thinking about it now, but if I oversleep I get a headache. Only on weekends and a holidays, but sometimes if I slept and then wne back to sleep I'd get a headache if I went to sleep again. Usually nothing a sharp coffee and some painkillers couldn't cure, but still. Anyone else get this? Hasn't happened for years now.
Some 4 or 5 years ago I remember thinking there was a morning where I felt like I both under-slepped and over-slepped. lol
