urinary tract infection
"Took this for a urinary tract infection and I've had them before, taken other medicines.  This appealed to me because it was a three day deal. Started my first dose Thurs evening and everything was going pretty smooth.  I ended up having to leave work after two hrs on Monday morning  because My body was shaking uncontrollably (more hands than anything).  I was nauseous, which I pretty much felt everyday but more so the last.  And almost like my head was spinning, like I was going to faint. The shaking was the worst though."
