I know this doesn't answer the original question, but I would urge anyone who has a loved one who has a snoring problem to convince that person to see a doctor and have a sleep study done. Not all snoring is indicative of a problem, but a heavy, loud snoring could indicate obstructive sleep apnea. Your body becomes starved for oxygen because part of the passageways become obstructed and you wake up and snore to get air in.
Not only is it not conducive to a good night's sleep to being constantly woken up (even though you may not consciously realize you are waking up), but it is also dangerous long term to the health of your heart and brain.
I had my study done about 7 years ago and they found I stopped breathing around 26 times per hour. I've been using a CPAP ever since. The first six months to a year can be rough, especially as you have a huge sleep deficit, but I can't sleep without my machine now and it travels around the world with me.
