sinusitis
"I was given a 10 day prescription after sinus surgery. The pros are 1) I only have to swallow one pill per day 2) It doesn't bother my stomach (other antibiotics have in the past) and 3) I've not gotten a yeast infection. The con is that it seems to totally dry me out. I take it in the evening, and my mouth/nose/lips are incredibly dry regardless of the amount of water I drink all night long. It is uncomfortable enough to keep me awake. I also experience dryness during the day, but not the same severity."
