Saliva

Hi, Does anyone else produce loads of saliva? I constantly have a mouth full of the stuff so talking is awkward (I constantly have to keep swallowing) and I don’t drink anything like as much as I should because I very rarely get thirsty. I only drink water as my bladder can’t tolerate hot drinks or juice. If I have a hot drink it’s usually just a few sips of very weak herbal tea. Anyone know of anything that could help? Heather
