The euphoria experienced after consuming large amounts of sugar or caffeine. The effects of sugar high are commonly exaggerated by people who compare it to the effects of pot, alcohol, and other drugs. These people are usually idiots. While sugar high exists, its effects are, in fact, really tame, and may include dizzyness, a bit of insomnia and nausea. It lastes for a couple minutes, or wears off after you take a shit/throw up.
I ate 5 candy bars and got a sugar high, I threw up and then I felt okay.
