As I prefer coffee far more than tea, I have one cup of tea after I wake up while checking my emails.
I will sometimes have another mid morning and that is about all.
The only other time I will drink tea is if I am at a friend's house and they drink Newcafe, then I have tea as I hate instant coffee.
Most of my friends do not have percolated coffee, so that is then the exception to how many I have per day.
Would not make one in the night if I cannot sleep as stay in bed.
