My caffine pill I took made me woozy. Do you think this will happen everytime? I never knew...

It's highly addictive. Don't take it.

The trouble with caffeine is that a person can build up a tolerance to it very quickly, but the more caffeine a person needs to get the same energy boost, the more danger there is of an overdose. I overdosed on caffeine a couple of times, and it was scary. The first time I overdosed, my whole body started shaking violently, and I didn't even realize at first that I was shaking. It just seemed like the whole room was shaking. The second time, I felt like two strong hands were squeezing my heart very hard and throttling it.

The effects might be a little more mild if you take it again, especially if you cut the pill in half, but this is something that you have to be very careful with, if you decide to go this route. As someone else said, it's way too easy to overdose because it's so much easier to take multiple pills than it is to drink too much pop, or even too much coffee.
