Caffeine has its perks but it also has some potential side effects.  So when should you consider cutting back on your caffeine intake?

Well, for most healthy adults, moderate doses of caffeine — 200 to 300 milligrams (mg), or about two to four cups of brewed coffee, a day isn’t harmful.  However, daily caffeine use of more than 500 to 600 mg a day, may cause the following side effects:  Insomnia, Nervousness, Restlessness,  Irritability, Stomach upset, Fast heartbeat, and muscle tremors.  If you experience 2 or more of these symptoms for an extended period of time, it may be time to limit, or even eliminate caffeine from your daily routine.  For more information on the effects of caffeine, check out:
