I wake up every night, sometimes half a dozen times with a parched mouth, throat, tongue, roof, even high up on my gums. First I tried to increase saliva, although I have plenty during the day, by drinking more, using an alcohol free mouth wash, chewing gum, artifical saliva, but I don't think saliva shortage is the problem. Whilst my wife tells me I'm a quiet sleeper, she says my mouth is wide open when I'm asleep, even though my nose is clear. It's almost as if my brian tells my nose to have a rest after breathing all day and tells my mouth to take over. l've tried creating a suction with my tongue to keep my mouth closed, sticking a fist under my chin whilst I drop of to sleep, I've even used a pair of my wife's tights to tie my chin up, all to no avail. I thought that tying my chin up might work, but I was still trying to breath out of my mouth and was making a noise like a horse. Might try a vestibular shiels or chin strap, but any advice would be grarefully received.
