Can't sleep, was it something I ate?
Can't sleep, could it be all the tea?
Can't sleep, or the carbs on my plate.
Can't sleep, what's happening to me?
Can't sleep,but I'm so very tired.
Can't sleep, but I went to bed on time.
Can't sleep, but it's my greatest desire.
Can't sleep, It's a crime.
Can't sleep, my brain's still working.
Can't sleep, too many thoughts.
Can't sleep, my mind's surfing.
Can't sleep, all hope is lost.
Can't sleep, I'll be tired tomorrow.
Can't sleep, even though I try.
Can't sleep, wish my memories would burrow.
Can't sleep, I wonder why.
