Caffeine-containing products such as NoDoz are often used as stimulants, and the effectiveness of caffeine as a diuretic depends greatly on the amount that is used. However, care should be taken as in very high doses the compound can cause a state known as caffeine intoxication that can lead to nausea, coma, convulsions and, in the most extreme cases, death, Diet.com reports.
