Doxycycline
bronchitis
"Had no issues with this antibiotic, currently taking a 7 day course for a chest infection, have noticed a difference, before hand I was unable to sleep and hadn't eaten in 4 days as all the coughing was making me throw up and keeping me awake, after the first 2 days of taking this it calmed that right down and finally was able to get a good night sleep and eat. I'm currently on day 4, cough is still there but not half as much, also not as aggressive. Ribs are no longer in agony from the coughing. Personally I have had no side effects. I was told you have to take the tablet with a full glass of water and have done it both with and without food on my stomach and no difference. Must just effect different people in different ways"
