@moragsmum The body usually produces from 2 to 4 pints of saliva each day .. that saliva helps make things easier to eat, helps with good teeth, and many other good things.. My dentist says I produce a lot of saliva that gets in their way but they just vacuum it out and all is well. I had a lot of GERD and I had a botched surgery that gave me Post-operative gastroparesis... now I am so thankful for that saliva as I have to eat everything with a lot of liquid, sauce, gravy or such..
