I got a special type of mouthguard/nightguard/bite splint, or whatever this thing is called in English, that holds my lower jaw in front when I sleep, basically an underbite. This way, I can breath more easily, my wife says I don’t snore anymore and I don’t wake up in the middle of the night. Sleep apnea got way better. Been using it for several months now, so I don’t know what years of usage will eventually bring, but for now I’m happy.
