Me, too. Diagnosed with chronic insomnia that I've had since I was born. Average about 4 hours of sleep a night. Longest I've been up is 4 days straight, and I also never feel sleepy. People are always surprised to hear that there's a difference between being "sleepy" and being "tired" and that even when you're absolutely drained sleepiness can escape you.

I'm still young and healthy so I feel "fine" most of the time, even when I'm extremely sleep deprived, but I am a little worried what the effects of my sleep deprivation will be on my body and mind in the long run. Without Zaleplon I can't sleep. I could lay in bed for days and never fall asleep.
