She has this at all meals and when she drinks liquids or just moves having her use two pillows at bedtime or she keeps us up for hours coughing and blowing nose. Most times we sit her up in chair for 1/2 to hour until it stops. She has dementia/alz. and just diag. with acid reflux. Nothing is helping. Need advice. She is 96 and doctors just seem to pass it off, I think it is because she is old and they really don't care that much.
