Must find the motivation to study!

I have one of my most important exams tomorrow. I have no motivation right now to study. I didn't sleep well last night which is a total letdown compared to the sleep that I had last night. I even went as far as driving to the outskirts of town for some Timmy Ho's and that still hasn't given me the motivation yet! If I don't pass this exam, the three months that I have spent here in ahhh ummmm Saskatchewan will be a total waste of time. I am fighting with words again. This is not a good sign!!
