My mouth drops open too because of a jaw implant gone wrong but anyway, CVS carries a good product called dry mouth gel.
It feels kind of slippery, but it will keep your mouth moist and you can use it as many times as you need to.
There is also a nice product called AYR nose gel that you can apply to the inside of your nose with a Q-Tip (or the tip of your finger) to help dry stuffy nose that 02 users sometime get.
I use a H20 water concentrater that you fill with DISTLLED water ONLY. This has been foud to be the best relief that I
have found to help. and the people that provide your equipment can deliver it to you.
I hope some of what I shared will be of some help to you, Spunky!
*HUG*
I do use the Biotin Gel from Walmart. It still seems like I am having to apply it every 3 hours. I also have that gadget to hook up the distilled water, I just never did it. If you think it helps I will hook that up is I can remember how. Thanks for all your info.
((Hugs)) to you too.
