Fates symptoms and conditions

I am taking Levaquin one time a day, 500 mg. for diverticultis. I have fibromyalgia so attributed symptoms of EXTREME FATIGUE to that but this is fatigue like I've never known. I can't do much of anything. I don't work outside the home so will just deal with it if it cures my infection. I'm using sleep meds too...but that could be fibromyalgia kicking in too. But fatigue is much worse. I hope it kills those bad bacteria!
