Need Creative Idea for bondage

[Abhisheksub]

I have been a very bad slave and a student. I must wake up in the morning and study. But this isn't what happens. I set the alarm at night, wake up and then fall back asleep. I need some idea of a dare or a bondage position that would keep me awake for 3 hours.
I want some technique of bondage that won;t let me fall asleep when I'm on chair sitting and studying. It may not be painful while i'm awake and studying but shall be extremely painful when I fall asleep.
It can be like a rope bondage to prevent me from falling asleep or some sort of bondage that would pain if I doze off. I'll be really thankful if your idea helps me.
