Still awake!

I have to be at a workshop by 9am. I want to sleep but can't. I hope I can wake up on time in the morning for the workshop. Maybe I will try to hypnotise myself:

"You are getting very sleepy, your eye lids are closing, you are almost asleep. On the count of 3, you will be asleep. 3, 2, 1. You are asleep."

Am I asleep? Rats! no such luck.
