For several years now I have been bringing up white phlegm. My voice is constantly hoarse and on occasions I have trouble making myself heard. I have been prescribed Omeprazole for 5 years now to alleviate the stomach pain etc. but feel other symptoms now I.e. Nausea, tiredness, aching limbs, depression ..... I am 82 (but still active!) . Have been told to continue with the medication but can you suggest a preparation to clear the throat.,thank you J.A.
