Why do energy drinks make me more jittery than coffee, even though the coffee I drink has significantly more caffeine?

The title says it all really. If I drink a small Red Bull with 80 mg it makes me twitchy, but a 200 mg coffee barely even affects me.

The way caffeine works is by blocking the signal to your brain that you are tired. Energy drinks also contain other ingredients that actually stimulate you including, usually, lots of sugar.
