What happens to caffeine, guarana and taurine?
It is because the level of addiction and the severity of withdrawal effects are both minor. I can drink tons of caffeine for weeks with few ill effects, and if I quit cold turkey, while I may want caffeine, it does not cloud my judgment, and the worst that happens is a slight headache for one day. Additionally moderate caffeine intake is not linked to anything as serious as liver failure in alcoholics or lung cancer in smokers.
