urinary tract infection
"I started 500mg at 5pm when I returned home from Urgent Care.  I was diagnosed with a UTI/Bladder Infection. I was severely uncomfortable, unable to empty my bladder completely and had spasms in my bladder.  By 11pm I could feel the pressure in my abdomen start to decrease.  After the 2nd does at 5am in the morning I am feeling better.  I can completely empty my bladder now and the spasming has stopped.  Levaquin is too harsh for me because my tendons start to ache, unable to sleep, anxious and restless by the 2nd or 3rd day into treatment.  I do much better with Cipro because side effects of feeling a bit restless don't kick in until about the 6th or 7th day which is a full treatment.
Just don't take with dairy or iron."
