Caffeine can alter one's health in many ways.
It is found in sodas, teas, coffees, and even bottled waters. Since our culture doesn't regard caffeine in the same manner as it does many other drugs, its powerful stimulant effects are often either underestimated or even ignored. Caffeine's kick comes with a cost. Gulp that beverage and you've got 'em. Similarly, it interferes with sleep patterns, and can disrupt a good night's sleep.
