I’ve been snoring since forever, it’s so loud that I have to sleep in a different room with my family. I’d tried Zyppah mouth piece and it only helped if I sleep sideways which is the same as if I don’t have it. For $99 it’s a great mouth guard for grinding teeth, but not really working in my case because when the mouth is opened, that’s when the snoring starts, nothing in the mouth can help it.
I’m going to order SnoreShield from Amazon to see if it helps, I think if you don’t open your mouth while sleeping, the snoring will stop.
