Question

Thats the just of it

Answer 1

Refresh doesn't cure sleep, so nothing would happen. But if a move like heal bell or something was used, still nothing would happen, as the status has not yet started, and therefore can not be cured.

You could switch your Pokemon before it falls asleep to prevent the sleep status from occurring.
