I just learned to sleep with my mouth closed and I watch my breathing during the day too, and avoid breathing through my mouth. This was difficult at first. Idk why, but I’ve read the musculature responsible for breathing gets weakened if you breathe through your mouth, because there’s a lot less resistance. But now it’s fine, and I don’t even snore anymore. Obviously this is down to individual physiology, so I’m not saying this works for everyone, but it did work for me. Costs $0.
