Ok, let's assume you have no issues getting a good night's sleep on a daily basis. Your sleep routine is optimal.
Even when this is the case, can you still wake up feeling worn out, or beaten up? Or as if you got a good night's sleep but you sure don't feel like you did?
Why do you suppose that is? After all, you did get a perfect night's sleep last night, right?
What do you think you need to do in order to "fix" the issue here?
What would it take for you to feel genuinely rested and refreshed at the start of any given day?
