i drink green tea first thing in the morning before breakfast and i have never fainted. i guess it all depends on the person.
I do the exact same thing! I have a tall glass of it as soon as I wake up every morning, I've never fainted either. Quite opposite actually, wakes me up and makes me feel great!
I love Green tea. I drink rougly 5-6 cups a day, I think the caffiene has made me completely addicted But I can't help it! I love the taste, hahaha.
