chlamydia infection
"I took 1000mg (oral tablet) of this drug after eating a plain rice ball and two slices of white bread. I was too anxious to eat a proper meal as I had heard of so many bad reactions to the drug. Drank about 800ml of water within the hour of taking the pills and went to bed immediately after. 
No nausea, no vomiting, no abdominal pain. Woke up 8 hours later and had one episode of very minor, painless diarrhea, which was in fact less severe than my usual reaction to lower but prolonged doses of antibiotics. No problems since then (now 12 hours after taking the drug). 
Will not know if it was effective for a few weeks, but given that there were virtually no side effects, I wouldn't be bothered by taking a second dose if needed. 
Don't worry."
