Brand of over the counter caffeine tablets. Used to prevent drowsiness. They are cute little pink pills, which contain 100 mg Caffeine alkaloid, plus inert fillers. "NOT TO BE GIVEN TO CHILDREN" is the big warning on the back. They are for occasional use only. Around exam week, is when I find them most helpful. They're a lot more handy than guzzling a whole pot of coffee to get you through the day. Yes, you'll be glad to know all the caffeine side effects are the exact same: shaking, restlessness, and inability to get to sleep when you finally get the chance.
