My mum, when she was working, would have about 10 - 15 cups of tea/coffee a day. This was largely because she did home help work and every time she would go to an old dear's place, they really just wanted someone to talk to.

Then she'd come home and have her 'normal' cuppas.

So THAT'S a lot.

I don't think 1 -2 cuppas a day matters.
