SleepQ+ has been part of my pre-bed routine for the past six months. I apply about one cm each night. If I want to speak or cough, it is very easy to reopen my mouth with a quick lick, and close it again to re-seal. Otherwise my mouth stays closed until morning. I am no longer awakened by 'snorts' several times each night. When I want to remove sleepQ+ it is easily wiped off. My quality of sleep has been greatly improved by using this product and I highly recommend it. It's simply brilliant.
