I had terrible post nasal drip and coughing fits last summer for a long time. I delayed a couple trips and skipped meals with friends because of them. The pulmonologist thought it might be contributing to all the tree in bud and mucus plugging on X-rays. He started Asteline and nasocort which helped a LOT with the fits. The ENT he sent me to gave me prednisone and AB's which has me pretty clear. Mayo is changing the spray to their triple spray.
During the months with the fits, peppermint hard candy helped
more than anything, including Hall's.
