I was on Nexium for about 5 years, followed by Tecta for another year or two. Then my doctor was on holidays and a locum was in his place, and she told me that if I had tried going without (I had) and experienced a flare up, it was because my body was adapting to not having the drug. If I held out for a few weeks I could see if there was a change.
I immediately stopped taking the drug, and had about a week of awful reflux. Then it went away. Now, unless I am foolish enough to eat more than a little bread, sugar or canned tomatoes in any form, I just don’t get reflux. I have often wondered just how many years I took that fucking drug unnecessarily because it was easier for my doctor to just sign the prescription and send me on my way.
