Did you give DGL a chance to work? I only had GERD symptoms for about 1 month and it took me a month using DGL very consistently along with being very strict with food and very small portions many times a day to get results.
Maybe you just didn't stick with it long enough.
You just have to forget about the food you love to get over GERD. I just don't get it, if you're suffering why would you care about all the food you want to eat. Just eat nutritiously for a while and heal your esophagus. There's enough information on this site for you too use to do so. Research back, I've posted enough things that I did to help myself cure my esophagus.
You will eventually return to foods that you love but for heavens sake, give up alot of things or else you will be in the drug after drug circle that many people seem to be in.
