An estimated 80 to 90 percent of humans start their day with a caffeine fix. According to research, some three out of four regular caffeine users are actually addicted to the substance. Although most caffeine drinkers swear by the quick jolt of energy caffeine provides, the drug is linked to high blood pressure, incontinence, and indigestion. So what happens when we go cold turkey and give up our morning cup of Joe?

During the first seven days without caffeine, 50 percent of addicts will suffer from nasty headaches. Although they can be remedied by over-the-counter pain relievers, many of these contain caffeine, so be sure to check the back of the box. Caffeine quitters will also experience trouble in the bathroom after losing the aid of caffeine’s natural laxative effects. They may also suffer from brain fog caused by the body going through withdrawals from the powerful stimulant.
