f you're taking in too much caffeine, you may want to cut back. The best way is to cut back slowly. Otherwise, you could get headaches and feel tired, irritable, or just plain lousy.
ry cutting your intake by replacing caffeinated sodas and coffee with noncaffeinated drinks, like water, decaffeinated coffee, caffeine-free sodas, and caffeine-free teas. Start by keeping track of how many caffeinated drinks you have each day, then substitute one of these daily drinks with a caffeine-free alternative. Continue this for a week. Then, if you are still drinking too much caffeine, substitute another of your daily drinks, again, keeping it up for a week. Do this for as many weeks as it takes to bring your daily caffeine intake below the 100-milligram mark. Taking a gradual approach like this can help you wean yourself from caffeine without unwanted side effects like headaches.
