Narcolepsy + Insomnia = Cranky Me

I can't sleep. In a little more than 24 hours, I'll be taking a three-hour exam to determine whether or not I receive my Master's degree. Today I did everything right, I took all my meds in good time, I didn't exercise before bed, and I didn't nap all day. I've been laying in bed for hours not sleeping. I am not happy right now.
