chlamydia infection
"I sadly got chlamydia again and was once again prescribed two 500mg tablets to be taken at once. After about an hour of taking them I felt like I was going to die, my stomach hurt so bad I couldn't walk and taking deep breaths hurt so bad, its a stomach pain i wouldnt wish on anyone. I'm surprised I didn't throw up because I came so close to losing it like 4 times. Please use protection from now on, I know I will. 

CAUTION!! DO NOT HAVE ANYTHING PLANNED FOR AT LEAST 3-4 HOURS AFTER TAKING!!"
