Yes, last week i was really sick with a sore throat and sinus infection and i took zithromax for 5 days. But i have been sick so much with these stupid sinus infections that some of the antibiotics don't work anymore. And yup, i do have a really nasty cough. And i know by smoking i am not making it better.
But your right, does that make sense. Because i still don't feel like i totally recovered.
