If your non-medical attempts do not resolve the reflux, then you should treat it medically because untreated acid reflux can cause esophageal cancer. You can first try Tums and/or gaviscon, and if this is not enough then a non-PPI, such as famotidine. (H2 blocker) If these don't work, then you should go to a PPI.
Keep in mind that if you have throat irritation, even if you've started medication it will take a week or two for the throat soreness to go away, so you need to give it that chance to heal and then see if it gets better with the meds.
