hot chocolate or hot chips?

It's 11:30pm. I had an exam today. I had an exam yesterday. I have an exam tomorrow. Thankfully, it's ancient Roman art, and I've already done most of the studying, but I'm still bloody exhausted and still have a lot to do and I think I need a treat of some sort to keep me going; tea, hot chips or hot chocolate? Decisions! Decisions! Just think, in 13 hours I will be FREE. From exams, that is. And only until December.
