Sinusitis
"I have had MANY sinus infections over the years, and Biaxin is the only thing that really gets rid of them. Yes, you have a horrible (metallic) taste in your mouth, are a bit loopy, and tummy isn&#039;t the best, but those side effects are nothing compared to serious sinus pain. I&#039;d rather be thirsty than feel like my head is in a vice all day!"
