Do you brush your teeth immediately after waking up in the morning?

Most of you brush your teeth before going to bed, right?

In that case, do you brush your teeth immediately after waking up in the morning?

As I get older, even if I brush my teeth before bed, my mouth feels very dry and unpleasant when I wake up in the morning. I am curious if you brush your teeth after waking up, if you don't really pay attention to it, or if you just rinse lightly.

If I brush my teeth after waking up in the morning, I end up brushing quite a few times a day, and I'm worried that brushing too much might also affect tooth wear.

How many times would be appropriate?
