bacterial infection
"I'm not sure how much of a rating to give for this drug. 



I am taking Doxy for a sinus infection and clearing of my chest, 2 a day for 7 days. I took my first two at a time last night and taken my first single dose this am. I still have a headache, pain in my neck from the chest congestion. I don't have stomach issues so far but I still feel crappy. I sleep with this medication, I had a great sleep last night and today slept all day, I'm still tired. I didn't read the information properly I did not take a full glass of water with the pills - oops. Didn't do anything bad though but now I know."
