At Starbucks I get a tall green tea frapp without syrup, without whip cream, and with extra matcha.
How many calories is this drink?

I have the Women's Ultra Mega Heart Vitapak from GNC and in the multivitamin it says there is 10mg of green tea leaf extract. I am curious how much caffeine this contains? Does anyone have any idea?

I'm doing homework lol. I haven't gone to sleep yet and I just finished the last of the coffee. But I have tea! I was wondering though, how much more/less caffeine is there in tea compared to coffee?

I have Bigelow (h/e it's spelled) green tea and a few others i think.
