I was on 80mg Nexium a day, depressed, gave up, no hope, etc. I'm sure you know what it feels like. I had gastritis as well, and acid was making it's way into my mouth when I slept.
In my quest to find the ultimate natural cure, I stumbled across Yang Wei Shu when looking at Chinese medicine. When I received it, I had results in 24 hours. No reflux, no bloated stomach. Thinking it was too good to be true, I cut my nexium down to 40mg and still no reflux. After four more days I stopped taking Nexium altogether and had zero reflux symptoms.
I continued for a month until the bottle was empty, and remained reflux free. After the bottle was empty, I still got reflux maybe once a week (and nowhere near as bad)- but this was a breakthrough for me. I continued without it for a few weeks with very mild reflux (enough to get by with antacids). I then made the decision to continue taking it, but only at half dose. That seems to keep it under control. I do occasionally take a few days off, but usually I have some mild symptoms return.
My doctor actually called me "ignorant" and "silly" as Nexium is tried and proven, whilst what I was taken was not. Well, all I can say is: if you're getting reflux on 80mg nexium, then in my opinion, Nexium isn't effective.
So, to answer your question- yes, I still take it daily, but at half dose. Without it, I would still be getting some symptoms. I actually have a perfect working LES, so I believe it is food allergies which cause my reflux.
My advice to you is to try it for a month at full dose- if it works, cut back to half dose. Consult your doctor of course!
All the best,
