It is 4:30am and I need to be up at 8.
Am I being unreasonable to think it would be better to just stay awake instead of going to sleep, feeling awful when I've got to wake up and knowing I will potentially sleep through my alarm.
I could easily fall asleep now but I'm dreading how tired I will feel when the alarm goes, that is if I wake up!
YABU - some sleep is better than no sleep regardless of the risk of sleeping through.
YANBU - at least you're awake now and won't miss your alarm, just go get a coffee!
