Joe and Teresa Graedon answer readers’ questions. This week: relieving indigestion with lozenges; the benefits of berries; grape juice is great, the sugar not so much.
Q: My 30-year-old son was diagnosed with GERD. He really struggled with PPIs (proton-pump inhibitors), but when he stopped taking the drug his doctor prescribed, he had rebound reflux.
