I have slept with one for about 10 years. Before I got it,
my husband got very little sleep with my loud snoring, andwhen I quit breathing, waiting to see if I would start
breathing again.
My Dr. also uses one. Said the first night he used his
he felt like a new person when he woke up. Sorry to say, I
never seen a bit of change in the way I feel, but I use it
faithfully because I know it is healthier for me, and gives
my husband some sleep and peace of mind.
