Pilocarpine
"I have sjogrens so have a dry mouth. I would give it 10, but I find only one drawback.  I can take only four per day and many days I could use just one more.  But this has really been a godsend for me.  I developed 30 small cavities during the time that I was not taking this (about one year).  And I was slurring my words so much because of the completely dry mouth - my husband actually thought I was having a series of strokes.
With pilocarpine I have my dental problems under control, and I have my voice and comfort back.  

My primary doctor did not know about this.  My rheumatologist did not suggest it, my dentist did not know of it...  I got on the internet and looked for a medicine that had the side effect of making my "mouth water" -- almost immediately I found this Rx."
