I had plugs put in 2 years or so ago. Each pair worked instantly, and like magic, and seemed to help for a few weeks and then stopped working, even thoughk, when checked, they were still there.
My new eye dr.saw that I hadjust one plug in. He took it out, and just put it 4 plugs at once, (smartplugs) I signed a waiver about how I might have too many tears. I was so excited, but so far I have had no improvement. I am so disappointed that I didn't get even those few weeks of relief.
don't read on if you're grossed out easily, but last night was the first night I slept well because I didn't have a dry mouth. Turned out the socket of my just-removed tooth was still bleeding slightly and giving me dry mouth relief. It's come to this!
Thanks for listening, this site means a lot to me, esp on my more hopeless days.
