Many who try pilocarpine do not get much help from it. While it may get a bit more saliva for you, I think that the point that everyone ignores is that when the gland is dead, nothing so far brings it back to life and production. Pilocarpine's course of action stimulates ALL the possible moisture producing micro glands in your mouth (which are numerous -think thousands of tiny pores- and do not just include the major salivary glands but those single pores that cover much of the mucous membranes of the oral environment). Note though that it is not a localized effect, and plan on sweating like a bull in heat. My personal attempt at using this stuff left me with more than sweaty pits, palms, and more private parts. It was a genuinely uncomfortable experience for the minor oral benefit. I will spare you articulating the BO issue that accompanies copious perspiration. Your mileage may vary......
