Got a problem during the night where I can't breather through my nose, I always breathe through my mouth and this leaves me with a very very dry mouth in the morning (I breathe through my mouth most of the day too, I have to actually think about breathing through my nose to breathe through it). I always wake up thirsty, with dry lips and tongue (usually split tongue and lip from the dryness) and with bad breath, all due to breathing through my mouth all night long. I've tried vaseline on the lips, but my tongue still splits and the dryness is still there obviously.
Anyone have any ideas as to what might be causing this and how to solve it? It's been happening for years but it's been really annoying me lately.
