What Happens When You Take Caffeine Pills & Alcohol?
The mixture of caffeine and alcohol can be toxic to your body. Caffeine appears to override the tiredness that occurs when you drink alcohol. It also delays your feeling of drunkenness. If you drink alcohol while taking caffeine pills, you are likely to keep drinking beyond your usual limits.
Considerations
The effect of using caffeine pills together with alcohol depends upon your body weight. If you are a teen or college student who has not yet built up a tolerance to alcohol, or if you are slender, you are likely to be more strongly affected by the combination.

The combination of caffeine pills and alcohol may impair your judgment more than drinking alcohol alone. The combination may distort how you perceive your limitations. For example, because of the caffeine's affect, you may believe you are able to carefully drive a motor vehicle, even though you have blood alcohol level above the legal limit.
Physical Effects
Most over-the-counter caffeine pills contain about 200 mg of caffeine per tablet. That's about as much as two cups of coffee. Caffeine will not help you sober up after drinking too much. Using caffeine and alcohol together may cause you to experience an upset stomach, nausea and vomiting.

A study done in 2006 found that about one-quarter of college drinkers try mixing caffeine and alcohol intake in an average month, according to Wake Forest School of Medicine. The researchers found that if you mix caffeine and alcohol, you are likely to leave a bar drunker than if you stick to alcohol alone. The combination can significantly increase your risk of personal injury.
