Drinking too much coffee, soda or other caffeinated beverages or taking too many caffeine supplements can result in nervousness, dehydration, digestive issues, a rapid heartbeat and sleeplessness. After the stimulating effects wear off, caffeine can also diminish the body's stores of energy. Neutralise the effects of excess caffeine intake if you find yourself feeling its effects. Several steps--from relaxation to eating--can be taken to help calm and soothe a mind and body that has been overactivated by caffeine. Consult your physician if you have any further concerns about heart or digestive issues.
Relax. Sit or lie down alone in a quiet space or take a walk. Listen to calming music, read a book or simply close your eyes and take deep breaths. Take a bath with essential oils. Aromatics such as lavender are known for their calming properties. Relaxing will help soothe your nerves and focus your mind on something else.
Drink at least two full glasses of water. Water will help rehydrate and cleanse the body and restore many depleted minerals.
Take a vitamin C supplement. Vitamin C will help the body break down the caffeine.
Take an anti-diarrhoea medication such as Kaopectate or Imodium if the caffeine intake has resulted in diarrhoea. These products are available over the counter and will relieve most symptoms of diarrhoea, including an upset stomach.
Drink a small glass of wine. Alcohol slows brain activity. A glass of wine will help counter the stimulating properties of caffeine. Avoid drinking too much alcohol because it can interfere with the process of renormalising the body.
Eat a healthy, hearty meal, especially if you are feeling lightheaded. Caffeine may have diminished your hunger, but it is still a good idea to eat something. Eat the meal in small amounts over time if you have an upset stomach and are worried about keeping food down. Avoid sugars because sugar will only restimulate the body. Food will absorb the caffeine and restore energy.
