I have a pattern which really works for me where I wake up, brush my night guard and brush my teeth with no toothpaste and then eat breakfast. That way I don't have the horrible mint toothpaste / orange juice clash I'm sure many of you are familiar with.
Then at night I floss and brush with toothpaste, and put in the night guard.
I used to make myself floss only every other day (like if I didn't floss last night I MUST floss tonight), which I highly recommend rather than sporadic or no flossing. But I recently upped my game to "every night except special occasions".
