This works! Diagnosed with sleep apnea, I could not handle the cpap masks and after i got a deep nose sore overnight I stopped using it. My husband was on edge because he would hear me snoring, but what really freaked him out was me gasping for air...He made me order this product and I was reluctant, but am SO happy I did ...I am not snoring nor gasping for air anymore. Thank you... Money well spent!!
