Coffee.
Lots and lots of coffee.
Seriously, what do you think I am drinking right now?
But apart from that;
2) There's this place known as shakeaway nearby that does the most INSANE milkshakes. You can put pretty much anything in them. My favourite combination is the banana milkshake mixed with a dimebar. It's the stuff of gods.
3) Dr. Pepper... ah how I love you. Not only does it taste great, but the vending machine in the library I often study at sometimes gets them stuck; if you select the right drink, the Dr. Pepper bottle will also break free, and you get two drinks for the price of one.
4) Child friendly forum, I won't say what this is. Dur hur hur.
5) Fizzy (or carbonated) water. Now, don't look at me like that. It's just... addictive.
