I'm 50+ This is really bothering me. It seems to be getting worse. It happens more so at night. It will wake me up. I can't seem to get a desent night sleep. My throat feels like its on fire but that nasty taste stays in my mouth and I can't go back to sleep. I also cough up something like a mucus its yellow and nasty. I am taking Prilosec 20mg. Thanks in advance.
