tonsillitis/pharyngitis
"On day 4 of 500mg twice daily of Clarithromycin for throat and chest infection.  Throat not as painful but not completely cleared yet.  The bitter taste in the mouth is VERY unpleasant and tinges' everything I eat.  Hard to sleep as the taste is worse in the night so very tired all of the time.  Furry, yellow tongue.  Hoping today is the turning point in recovery."
