Green Tea Makes Me Nauseous

I drink a lot of coffee. But I'm trying to cut down because I use so much cream and sugar that it can't be good for me. Since I still need the caffeine, I switched to Green Tea.

And now I remember why I don't drink tea. It makes me feel like I'm gonna throw-up. Seriously. I get dizzy, the top of my tummy starts rumbling and I wonder if I can make it to the bathroom in time before I start blowing chuncks. But the action never happens and after about an hour of drinking water I start to feel better.

Does anyone have any idea as to why this would happen? I thought it was because of the caffeine, but I already drink a buttload of caffeine and it gets me through the day, not the opposite. So I read up on it and found a study at the Linus Pauling Institute at Oregon State University, reading: "few of the participants reported mild nausea, stomach upset, dizziness or muscle pain "

A "few" participants. Why the hell am I the freako?

Any tips on good way to fulfill my caffeine addiction without making me fat or feel like I'm gonna puke?
