Caffeine

I have been noticing that my heart beat will race in the afternoon after drinking 2-3 diet cokes/dr. peppers. I finally decided it was time to figure out exactly how much caffeine I was drinking.

So today I had 1 can of diet cherry vanilla Dr. Pepper in the morning, 1 tall glass (I estimate 2 cans) of diet coke at Skyline Chili for lunch, and 2 more cans of diet Dr. Pepper in the afternoon. From 9am to 4pm I consumed over 210mg of caffeine. So how much is too much and how long does it stay in your system?

A dose of more than 4.5 mg per pound of body weight, or at least 180 mg for a 40-pound child, can cause nausea, vomiting, diarrhea, cramps, and muscle twitching. At my current weight, that means I should try to avoid 900mg of caffeine!

The U.S, Government has no recommendation for the maximum amount of caffeine one should take. But the Canadian government does. They recommend 300mg, roughly 3 cups of coffee, as a moderate intake of caffeine.

I didn’t exceed what Canada recommends today but I think perhaps I should cut down on the amount of caffeine I drink. Now, will Coke start making the flavored diets in caffeine free soon?
