I've followed about the same route you have in as far as acid reflux problems and breathing problems. It's quite common. Same as with PPI's. Seems we're all different and what works for one, doesn't another. Personally, they've only put me on Prevacid, Prilosec and Nexium but have switched me back and forth. As I understand, Nexium is the strongest leaving no down time (yeah, right) and with LPR taking it twice a day is recommended. Of course, it's supposed to stop the swallowing problems and heal everything up and yada, yada, yada. I actually have stopped the Nexium in the past couple of weeks and other than having heart burn (which, I thought I never had) eating some pizza on Tues, can't tell any difference. I'm trying this natural product that I was hoping would help me get off meds but who knows. Guess this certainly no answer to your question but at this point after having GERD/LPR for past 10 yrs, I'm open to about anything. I think we all are going to have to do and try every option there is and as you know, might work for you and not another. I'd sure like to know your results. I believe my Dr. on this one. It is a "chronic" disease and although there is remission periods (for some lucky people) it flares ongoing with the in's and out's of our daily diets, schedules, and stress.
Good luck to you.
