Concoction for Studying

Two days have simply flown by with me failing to achieve my objective of... *drumroll*... Studying. I mean, I don't even remember what I did yesterday. I didn't even get to shop today (thanks to an infuriating incident with the ATM machine). After glugging down one mug of green tea (a strong one, it had two tea bags) I am somewhat hopeful.
This brings me to my magical creation, what I call my concoction for studying. I know that's not a proper name, but whatever. It sounds like a potion that way. Anyhow, the concoction. Yes. I have shared the amazing recipe with quite a few people. By now your mind should be buzzing with curiosity. Without further ado, tis time to reveal the not-so-secret trick: one teaspoon coffee, one teaspoon regular tea and one teaspoon (or one tea bag) of green tea. Brew for a minute, and prepare your taste buds for the most awful thing they've ever tasted.
You don't even need to THINK of Retlin anymore. This mucky liquid is able to keep a normal human being up for at least six hours. AT LEAST. But alas, everything must come at a price. Without proper sleep before a test, you are more likely to panic on seeing new questions. More likely to forget things you already know and confuse them as well. I speak from experience.
So people, now that I've told you all of my secret, I've burdened you all with the great responsibility of handling it will. My advice would be to study good, study hard, but not study-I'm-gonna-cram-my-brain-to-death.
