Doxycycline
"I was prescribed this for tonsilitis and a nasal carbuncle/furuncle. Prescribed twice a day for 10 days. It got rid of the fever and sore throat after a day. The puss pockets on my tonsils are still there, but smaller, and I am on day 8 out of 10. I could not take this pill on an empty or even semi full stomach, or I would throw up. Even a banana an hour or so before dosing would not be enough to stop the severe nausea. Besides that no real side effects, except loss of appetite. Not pleasant to take because of the size of the pill and nausea, but worked."
