Interesting article on caffeine....

William is in a constant state of trying to cut back on caffeine... he is INCREDIBLY addicted. So when I saw this post I had to read up for him. He loves Diet Coke and apparently it contains significantly more caffeine than regular coke! Kind of crazy....
Here are the stats that came from this article!

Coffee

Coffee varies in caffeine content drastically, even in the same coffeehouse, on the same day. Everything from roast styles to brewing methods affect the amount of caffeine you get. The lighter the roast, the more caffeine it has.

• Starbucks (Grande) iced coffee, 16 oz: 190 mg. This is double-brewed. Without the ice it contains 380mg.
• Starbucks brewed coffee, 16 oz: 330 mg. Brewed coffee has 50% more caffeine on average than instant coffee.
• Instant coffee, 16 oz: 60-345mg
• Starbucks latte, 16 oz: 150mg
• Starbucks espresso, 1 oz (1 shot): 58-75mg

Tea

The longer a tea is steeped, the higher the caffeine content. If after the first steep, you add more hot water to the tea or tea bag, the tea becomes almost entirely decaffeinated.

• Starbucks Tazo chai tea latte, 16 oz: 100 mg
• Regular black tea, 8 oz: 40-120 mg
• Stash green tea, 18 oz: 78 mg
• Snapple iced tea, 16 oz: 18 mg
• 12 oz Nestea: 17 mg
• Decaffeinated black tea, 8 oz: 2 mg

So for all you caffeine lovers trying to cut back... maybe simply switching which product you eat/drink for a while will help! Also lay off the migraine medicine.  It makes sense why they contain caffeine since most people get caffeine headaches... but it's just seriously perpetuating your problem, because in 4 hours you'll just either have to drink some caffeine or get a "fix" from their medicine.
