Who knows some techniques to stop snoring?

what my dad did was instead of sleeping on his back he would sleep on his side and put some pressure on his jaw by his chin when he fell asleep so the muscles would stay there when he fell asleep(mouth would then stay closed after he fell asleep with pressure on it) and that solved his problem...but then his nose made a whistle noise, so he picked most of his nose hairs out, guess what!!!!, no whistling noise and no snoring, then after awhile you muscle memory will take over and you can eventually sleep on ur back again......well i hope this helped but if not buy one of those stop snoring things o put in ur mouth
