Are you overdoing it on caffeine? Even two large coffees can put you over the recommended limit of 300-400 mg./day.

Brimming with healthful antioxidants, coffee is good for you, but where java is concerned, it is possible to get too much of a good thing.

Caffeine overdoses are on the rise — thanks in part to mega-size coffees, and popularization of high-octane energy drinks. Though they taste like soda, energy drinks can have three times the caffeine. Signs of a caffeine overdose include heart palpitations, dizziness, abd. cramps and heart arrhythmia.

The stimulant can stay in your system up to 12 hrs., so drinking large amounts on a regular basis can lead to sleep trouble and exacerbate effects of stress like high blood pressure and irritability. Research also suggests drinking large quantities boosts the risk of atrial fib. — an irregular heartbeat that can result in increased risk of stroke and fainting. Limit your cups of joe to 3/day or fewer, and do not displace your daily intake of water with caffeinated beverages. Increased anxiety or heart palpitations are probably signs you should cut back.
