ever since last week, i've been drinking green tea frap, but only "tall", am i ok? or should i stop? =[

lol, it's my favorite drink! =]

..... is there too much caffeine in it that i should stop?

the caffeine comes from the green tea concentrate they add to that drink. It's produced in Japan and is a highly concentrated high quality green tea. The green substance is called matcha. If I were you, I would google that. I don't know the answer to your question.

Oh, matcha is used in Japanese green tea ceremonies and requires a whisk to make the hot green tea. Sorry but they don't make green tea fraps in those ceremonies.

There is caffeine in green tea, but it is miniscule - some brands it is half (55mg) the amount of an average cup of coffee. Nothing to worry about!

allot!!!!!!!!!!
