There's nothing picky about needing saliva. It can be very frustrating after a while to always be so dang dry!! I keep a tube of Oral 7 gel in the car, office and home. When I get bad I just squirt a dab in my mouth. This is the only Oral7 product I can tolerate. The tooth paste and mouth wash light me up like a firecracker. They are not supposed to burn but my mouth is still super sensitive. The gel is very soothing and gives some temporary relief.

I read about some of the prescriptions available for dry mouth but they had some draw backs and side effects that outweighed their benefit for me. If you are getting real bad, that may not be the case. You may want to bring it up to your doctor again based on your current symptoms.

Good luck!
