Yes, we are. And the word "cuppa" is part of the English language.

I heard the phrase a lot when I was in England. As far as 'over-consuming' tea, there are some people that would tell you that it is not possible, that you can't drink too much tea. As it is, the English drink it a lot - about as much as Americans and Europeans drink coffee. Whether that is too much will obviously depend on who you ask.

"Cuppa" is used in Australia too. I am sure that there are just as many people in Britain who like coffee. Don't believe everything you hear about a country:)

It is used but not as frequently anymore. The British do not drink tea all the time. In the UK the tendency is to drink tea or coffee in the morning but then move on to other drinks such as water, soft drinks. There is a big move towards healthy living in the UK so many people are giving up drinking both tea and coffee.
