Ok, it seems that those coffees I was talking about earlier really were drugged. No wonder they made me feel a bit weird! I was just told earlier that sometimes they do drug the coffee on the street...

I knew they were too good to be legit!

[EDIT: They weren't drugged. Other than being made from some very strong coffee. I just drank way too much caffeine way too quickly. They put in a lot of sweetened condensed milk so you can't really taste the caffeine.]
