Stopping the snoring epidemic! Guess what?? It can't be stopped, short of surgery, but it can be tamed. Yep, I'm a snorer too. My ex used to get me to take Sudafed tablets each night - she said it cleared the nasal passage. Also, no alcohol at night, this induses heavy breathing. Nasal sprays work a little, but these can damage the nasal tissue if prolonged use occurs. Try buying different height pillows to adjust his neck for a clear breathing passage, and keep the one that works! Keep him on his side, and a pillow put behind him will help him do this (some people say tiew a tennis ball to his back for this, but it's f***n cruel).
Good Luck!
