This is a little long, and a little off subject, but its funny.
When I took o-chemII, I sat with this guy who swore that he took tests better when he was hung over. Well we had afternoon tests for that class, so the day of the test he would start drinking at 7am, and by the time 3pm rolled around, he'd be hung over, and he would take the test. Well, when finals rolled around we had an 10am final. Turns out he started drinking at 6am, and he was still REALLY drunk when he showed up for the final exam, not to mention he was an hour late. So he came in late and asked the professor if he could still take the test, but the professor obviously smelled liquor on his breath and told him no. So the guy starts yelling at the teacher, making a scene, but they left the room shortly after.
Moral of the story: make sure if you want to be hung over for a test to be hung over, not drunk.
