I went to Starbucks yesterday morning before school to buy some coffee. I was so tired, so I just asked the guy "How many shots of espresso can fit in a venti cup." It turns out to be 20 so that's how many I bought and drank. What ever you do, never be an idiot and copy what I did. During 1st and into 2nd period of school, I was SO hyper and I started twitching and being crazy like. Only 2 hours of hype. After that I completely crashed. I could barely stand up and I felt so nauseous, but couldn't throw up anything. Still into today, I don't feel so well so I stayed home. Just warning you guys that more than 4 shots/ounces of raw espresso wont do anything more than give you a major crash. Not to mention I loaded it with sugar until no more could fit in the cup.
