Sour,Dry ,sticky mouth 8 months post Nissen surgery.Please advise am ver very worried!

I note that your message has gone four days without a reply so thought I would do so. I have no medical qualifications but am going through the same ordeal. I too had a Nissen done , for the second time, last June, and decided to remain on ppi medication twice a day because I was still getting some heartburn. I am wondering if you have gone back to the surgeon for follow-up assessment? Having had this operation twice now, I have somewhat lost faith. The surgeon did his best to repair the valve but it still leaks at night when I am lying down and unconscious. A good night’s sleep is a thing of the past. I usually only get three or so hours a night at most and have to raise myself up to stop the reflux. As for the teeth, my dentist just gives me tooth mousse to put on my heavily eroded and very sensitive teeth twice a day. I am 65 so am probably worse off than you in that department. She says because of the acid reflux, things like crowns, veneers etc would not stay bonded. I think I am going to get a second opinion from somebody else, re my options.
As for long term management of reflux, I just intend to stay on ppis and hope it prevents me from getting esophagul cancer. I have lost faith in the medical profession coming up with any radical improvement. Sorry to sound negative, but there just comes a time when I have to accept that my body is wearing out.
