I would concur with lightseeker's suggestions before seeking an anticholinergic. A very learned physician friend once taught me "mother nature never does somethin' for nothin' ", and to fool with compensatory mechanisms without reason is to court danger.
I would try to do intentional swallowing multiple times daily for a few minutes each time, in the event that you do not involuntarily swallow frequently.
After a few weeks of practicing this, your subconscious mind will pick it up
and it will take place automatically.
Should you have such an issue , the medication or procedure to correct your hypersalivation, may do more harm than good.
Adequate saliva is vital for digestion, ph balance and immune function.
Even if salt has gotten a "bad wrap" , eating some dry snacks with unprocessed sea salt throughout the day, might help.
Try making your own dry snacks.
Avoid any saliva stimulating foods, like sweet, sour etc.
Should these suggestions don't help, then consider seeing your doctor.
Best wishes,
Niko
Please talk to your doctor. There are medicines called anti-cholinergics that can reduce bodily secretions, including saliva. In profoundly severe cases, surgery can be done to remove some of the salivary glands in order to decrease saliva production. Your doctor can evaluate what treatment is right for you.
