ImLily,
I used to take 40 mg Nexium a day. I weened off of it over a period of 6 or so months. I started taking an OTC Zegrid once a day supplimented with Gaviscon. I probably should have gone from 40mg to 20mg of Nexium before doing that but I did not want to go back to the doctor for that prescription. I took the Zegrid for about 2 months, then I went to an OTC Prilosec and cut it in half with a pill cutter. I took that for 3 more months. I then was able to start Pepcid AC twice per day and that is what I continue to take. I also have a very strict diet (no gluten, no lactose, no trigger foods etc) and I drink Alkaline water. I also take some other vitamins and digestive enzymes. I am dealing with IBS symptoms from the years of PPI use, so I am still nursing my system back to health.
