Hypothermia !

I have a chronic bacterial infection for which I have taken Avelox / moxifloxacin in the past without any significant adverse side effects. This time, however, about an hour after taking the first dose I got the "never felt so sick in my life" feeling others have reported here. I got into the bathroom and barely had the strength to get up off the floor to the toilet to void my intestines, alternating with throwing up in the tub. Then I started violent shivering, teeth chattering, mitigated a little by a heavy bathrobe and blanket, in a room that was already at 78 degrees. My oral temperature measured only 89 degrees! After about 6 hours all this subsided enough for me to get into bed for a fitful sleep. Fortunately I seem to be back to normal the next day.
