sinusitis
"Took this drug (5 day dose) for a sinus infection. It did clear up the infection but the side effects were horrible. I got dizzy, had a horrible headache, felt nauseous and at one point even vomited. Each day was agonizing, and I think I could have taken something else easier on the body for a minor sinus infection. I finished my last dose two days ago but I'm still feeling the dizziness. I hope it goes away soon."
