I am having the same problem. The Prilosec OTC (20 mgs) relieves most of my symptoms but I still get the throat burn here and there; especially right after I have taken the Prilosec. I've tried 40 mgs of Nexium and suffered debilitating side effects. I was in bed all day with diarrhea and nausea and terrible stomach pains - much worse than any heartburn I have ever experienced. When my throat burns, I take two Tums which really does help but I would rather just take my one pill in the morning. I am going to try the DGL licorice to see if that helps at all. I have asked my doc for advice but so far she just wants me to try another 40 mg drug like Protonix. I don't want to take another 40 mg drug because I'm afraid of getting so sick again. I have asked her to prescribe me Prevacid in 30 mgs to see how that might work.
Sorry but even though I can comiserate, I don't have any answers.
