I think I remember using the slippery elm? Have tried every other thing out there! I would lose my voice for weeks and months at a time so I have more the LPR problem and fight the symptoms daily. I must not have gotten very good results or I would remember but I was recommended to try slippery elm by a friend who sang in a band. If you suffer more from GERD, which I have too
licorice may help you more than slippery elm. Like you, I've been on Nexium (and many others) over they years and start feeling like it's not working so searching for alternative meds constantly.
Good luck and hope you are feeling better.
