It's very difficult to control your dog's behavior when you're not there or cannot supervise, such as when everyone is asleep. As others mentioned, you need to confine him when nobody is watching him so he has no access to things he can destroy. Crate him when you're gone and at night, or at least keep him closed in the room with you while you're sleeping.
We've had dogs that never went through a destructive chewing phase, we've had dogs who had horrible chewing phases but eventually outgrew it, and we even had one that seemingly outgrew it but then had a later, second chewing phase months after she'd been fine. She did ultimately outgrow it again, but I wouldn't trust a GSD unsupervised for a good year and a a half if not longer.
Halo is 8 and will still chew occasionally. Fortunately not furniture, books, shoes, or rugs, but anything that may have touched food is fair game, such as potholders. She is also a big fan of toilet paper, which she will eat right off the roll.
