bronchitis
"Have used Z-pack before with much success. Usually feel better by day 3. But this time chills, aches and coughing seem to be coming back on day 4. Feel a little woozy and weak but the meds make me not mind. Still feel better than I did before I started taking it. This is also my 3rd occasion to take the Z-pack in the last 2 years so I hope I'm not building up a resistance to it."
