Don't know which is worse, the complete blockage in my sinuses, or the Biaxin. This is the second course of antibiotics I've taken this month to cure it and this antibiotic is the worst.....metallic taste in mouth that never goes away and wakes me up at night to remind me of it's every lasting presence, diarrhea, constant upset stomach (like I'm hungry, but not), yeast infection - the only upside to it is that my moods are better (not worse). I only have 2 more days to go. My provider told me to reduce my Biaxin to 1 perday instead of two (to cut out the metallic taste), but I'm just gonna suck it up and finish the meds. Sounds like others have similar complaints about the drug....which they could fix the metallic taste and the diarrhea - then I'd be happy.
