Obsessed with tea

How much tea is too much? I read the label I don’t see any ingredients on the pack it’s the luzianna tea. I’ve had two cups today I do put quite a bit of sugar in it but definitely not as much as a soda. It’s the only thing that settles my stomach. Water and juice or anything else makes my stomach turn. I steep the tea in spring water but I jus wanna know cause it’s so good and it doesn’t leave me aching like juice does or nauseous like water does.
