Many people use caffeine as a morning necessity or an afternoon pick-me-up, whether in the form of a strong cup of coffee, a highly caffeinated soft drink or a variety of black or green teas. However, since it effects the nervous system, a caffeine overdose can result in the jitters, and the wakefulness and alertness you seek to gain from caffeine can result in a scattered anxious feeling instead.
Eat a hearty meal to help absorb some of the caffeine in your system. Caffeine on an empty stomach can result in the jitters. After eating, the blood rushes to your stomach and results in a tired feeling that will help you relax and reverse the caffeine effects.
Drink a lot of water. Caffeine is a diuretic and causes dehydration. Rehydrating will reverse some effects of caffeine on the nervous system.
Drink herbal teas. Chamomile and valerian root tea are common natural insomnia remedies and will calm the nerves.
Go for a run or brisk walk outside. Not only will the fresh air and exercise help keep your mind off the jittery effects of caffeine, but you will burn some restlessness and calories at the same time, which will help you relax when you get back home and back into your routine.
