It's weird. Usually, I need at least 8 hours (rarely ever get it) to wake up not feeling tired, and I'm always wrecked during and when I get back from college.
But on Thursday, I slept 5 hours during the day and as a result couldn't sleep until 4 am Friday morning. I had to get up at 7, so that was 3 hours sleep. I fully expected to doze off in lectures (as usual) but it was interesting enough that I actually stayed awake. I felt fine, NT-ish even (I get more AS when tired).
I figured I'd crash once I arrived home, but nope, fell asleep at 2am and got up at 8. Was active the whole day and now it's 2.30 Sunday morning...
This is really strange for me. I haven't been drinking more caffeine than usual (2 cups a day) and wonder if it's linked to the bout of sunshine we've been getting for the past few days. Or perhaps sleeping for an unbroken period on Thursday afternoon 'cured' my exhaustion. I feel 'buzzed', even though I know I'm probably wrecked.
Anyone else get periods of sleepness like this? What triggers it?
