I also
used to have a snoring problem, and have a close personal friend who is a dentist...
All you need it to go to you local pharmacy, and buy
any generic sports mouthguard.
CUSTOM FIT and similar bullshit, is about the same as
the separate C class hosting myth -- designed to separate the gullible from their money!!
A generic sports mouthguard - $10 to $15 - will reposition your jaw all you need to prevent you from snoring (which is not very much) ... and will not cause you any discomfort, unless you have a severely deformed jaw, in which, a sleeping device is the least of your worries.
I buy a new "cheapie" sports mouthguard maybe every 4-5 months, and I can proudly say I have been SNORE FREE for 6 years now!!
THE SAME CURE WILL WORK FOR BRUXISM (grinding your teeth while you sleep) TOO!!!
But most dentists will not tell you this, as they get paid - quite handsomely - by dental companies, to push their $60 - $300 devices ...
