sinusitis
"Third time taking a 10 day dose of this medication for reoccurring sinusitis. After the 1st day, I immediately get relief from this medication which is great and around day three I usually feel almost 100% back to normal but I do experience the metallic taste in my mouth, upset stomach this time around for some unknown reason and all three times I developed yeast infections (never had one in my life before until I took this medicine, I also take a daily acidophilus supplement which does nothing for the yeast infection in my case). For those reasons I am not a huge fan of this but am allergic to penicillin and sulfa drugs."
