I can't sleep, because i produce too much saliva. My throat is scratchy and hurts, and my nose is clogged so i can't breathe through it very well. It's impossible to sleep, and I think the cold weather is to blame for all of this. Is there anything I can do to stop the excess saliva? I've tried eating peanuts, gargling salt, spitting it out as it comes, and brushing my teeth. Nothing seems to do anything.
