If you have an acid problem you must try cabbage juice. I strongly advise you to research it and give it a try. I also had an acid problem and it was the only thing that worked.
It probably sounds really weird to you but just research it.
If you have an acid reflux problem that would mean you need to completely change your diet around. No fast foods, no fried foods, no greasy foods, no fatty foods, or chocolate, soda, etc, etc. Acid problems are usually caused by bad eating habits and stress.
Do you feel like your under a lot of stress? It could be anxiety related.
Also research sleep apnea. It could be that to. Talk to your doctor.
