Leslie, I understand your hesitancy. As adults, we take our morning jolt of coffee for granted. But caffeine is a stimulant and can have adverse effects if taken in excess. Our ER has seen children coming in with heart palpitations due to drinking numerous "energy drinks" ... most of which contain caffeine.

If it helps ... remember that Tylenol taken in excess can lead to liver failure and death (yet most of us think nothing of popping of couple of them for minor aches).
