[food] caffeine in food and drinks

I'm a heavy coffee drinker, and it's really tough for me to quit coffee.
Today is the third day of finding my pregnancy, I started eliminating caffeine as possible. Here's what I do now:

1. Cut my 6 cups of coffee into 2 cups, but make them with half milk or water, so I take only 1 cup of coffee in fact. (that kills me, I'm sleepy all day)
2. Cut all chocolate bites and other soft drinks such as cola.
3. Leave the first brew of tea to Alan my husband. Only drink the lighter infusions. Today I only had macha (green tea) instead of oolong tea. Since macha is grind green tea leaf, I'm guessing it has more caffeine than other green tea, because you're drinking the leaf. But as the figure shows, tea is nothing like coffee, I think I'll just stay away from black tea for the first trimester.
4. God, it's really hard.

*Coffee, Tea and Baby Makes Three(From Sean Paajanen, about.com)
"Most people are quick to agree that pregnant women should cut caffeine out of their diets. But current research has shown that a moderate intake of caffeine won't do any harm to developing fetus. Moderate intake would equal approximately 3 cups of coffee per day (300-400mg of caffeine). Of course, you can't forget to count the hidden caffeine in soft drinks and some over-the-counter medications... "
"Caffeine is a stimulant, and an addictive one at that. It has the same effect on your baby as it does on you. If nothing else, high caffeine intake during pregnancy will create an addiction in your child and force them to suffer withdrawal symptoms once they are born. Some studies have also shown a higher rate of miscarriage and low birth weight babies when the mother has had more than the 'moderate' amount of caffeine mentioned above."

*Caffeine: Pregnancy & Fertility(From Robin Elise Weiss, LCCE, about.com)
"A study in 2007 showed that in the second half of pregnancy, a moderate intake of caffeine (3 cups of coffee or less) had no effects on pregnancy."
"Most practitioners will tell you to err on the side of caution and avoid caffeine or cut back on your caffeine intake. They agree that while trying to achieve a pregnancy, during pregnancy or while breastfeeding you should try to limit caffeine consumption to about 300 mg per day. However, there are very few people who can tell you how much caffeine that is, partially because of hidden sources of caffeine."

"n addition, caffeine increases the risk of pregnancy complications, such as gestational diabetes, pregnancy induced high blood pressure and leg cramps."
