I have a cronic cough which coinsides with a lot of flem I almost always chock on what I eat chocolate, milk, ice cream are much worse. It becomes difficult to breath and it feels like my throat closes. I have had my esophagus tested 3 different times and its totally perfect. I have been on omeprazole for 3 months and it did nothing when I go to bed at night I always cough when I lay down so I always have to get up and spit out all this flem
