no doze 

Over the counter pills (usually caffinated) consumed with the intent of keeping one self awake. Commonly exaggerated to be a very potent substitue for sleep. In reality one tablet is the equivalent to two cups of coffe.

Man, I'm glad I took that no doze before class today. I was so sleepy.
