chlamydia infection
"Took two 500mg (1,000 total) in one dose. A little stomach pain but was able to sleep it off. No other side effects. The key to taking this antibiotic is to EAT EAT EAT. Eat something before and eat something after. And drink an entire bottle of water and then some. You'll be fine! Most people only share negative reviews but my experience with the antibiotic was just fine. And I have the worst anxiety. Just eat and drink water, and you'll be FINE."
