You must discuss it with your dr. A scope of your esophagus can tell if it's weak.
I personally am doing the Shaker exercise to help strengthen the LES. My dr says it won't work but doctors have been wrong before. Go to the website http://healthlink.mcw.edu/article/907444461.html and you can read about it.
I raise my head for one minute and then rest a few then raise again for one minute, then again. Do this 3 to 4 times a day. Might as well try it and in 6 weeks maybe there will be a difference.
We have to do all we can to try and get off meds. All the best....
