A couple of weeks ago I developed a cough, primarily at night. I can't sleep well because of it. I cough when trying to go to sleep, coughing wakes me up when I do go to sleep, and I keep coughing and can't get back to sleep. I have GERD with Barret's, been on PPi's since March, currently on Nexium. Cough lozenges seem to sooth my throat, but cause more coughing from my stomach. I sleep on a wedge, eat carefully and not within 3 hours of bed. I can't speak loudly, and have lost my singing voice. Any suggestions to ease the cough?
