Hello!
For the past month and a half-or so- I don't get tired until about 4:30 am, each morning. This happens to me quite frequently over the past year, but I still don't know why this happens. I have to wake up at 7:00am for school, but when I wake up, I'm fully rested and ready to go.
During last period at school, I get really sleepy. It's hard for me to keep my eyes open. I get a 90 in that class(even though I'm asleep most of the time) so my grade is not an issue. I don't know why I can't sleep at home.
