I'm 3 years out and my biggest problem is chronic dry mouth. I could not speak because my mouth would painfully glue shut. I had to get up at all hours of the night to sip water. I couldn't mow the lawn or exercise because my mouth would shut down in seconds. Well, I started using the XEROS Dry Mouth Pump and wow did it ever turn things around. I can now talk as long as I want. I sleep like a baby and I can now cut the grass and do my exercises. So things are looking pretty good. I have leather neck too but that ain't nothing. It's starting to loosen up a bit (from neck surgery).
