Once in a while, I go to the movies.
Once in a while, I eat junk food.
Once in a while, I take a power nap.
Once in a while, I go for a run.
Once in a while, I read a book.
I use Zoom once in a while.
I have a late-night snack once in a while.
I have food delivered once in a while.
I have trouble sleeping once in a while.
I sleep in once in a while.
