Stop smacking!😡🙉

Does anybody else's husband make annoying smacking sounds in his sleep?! It sounds like he's eating or chewing gum or something but it's annoying the crap out of me! I have tried ear plugs, sleeping with a pillow over my head, facing the fan that I always have turned on to sleep...nothing is helping and it wakes me up in the middle of the night MULTIPLE times!! Not counting the times I have to wake up to pee!😑
