Do a search of my postings....DANIE....you will get all the information on DGL etc and you can try and see if you can be helped by trying DGL and other methods.
DGL is a natural supplement...the high blood pressure part of the licorice is removed therefore it should not interfere with blood pressure. I got all my information on DGL from Dr. Weil's site (a US medical doctor, Harvard trained and well regarded) and that gave me the confidence that it was a good product to use.
I healed myself of GERD (caused by taking ADVIL at night and sleeping exclusively on my right side due to a left side injury). I only had GERD for one month but it took me over a month to heal my esophagus.
The very least you can do to help yourself is to SLEEP ON YOUR LEFT SIDE (acid from your stomach cannot seep up into the esophagus if you sleep on your left side). That does not mean sleeping on your stomach on the left side or on your back......YOU HAVE TO SLEEP ON YOUR LEFT SIDE. Use a pillow (vertically or a body pillow) to train yourself to do so.
