Levaquin and hard to concentrate

I am on Day 3 of a 7-Day treatment with 500mg of Levaquin This treatment is for asthma related breathing and coughing issues .So far , hot flashes, headaches , nausea, back muscle pain, leg muscle quivers, and a feeling like Im drunk or in some type of stupor; or fog........hard to concentrate and focus on anything for more that 2-5 seconds. Wheezing is back , even after Ventolin treatment .

I just got out of the hospital a few days ago. I received Levaquin intravenously. I am now taking a weeks worth of pills. Reading these entries is very disturbing.

I have expereinced aches in joints, but I relate that to being stuck in bed for four days doing nothing.
Other than that, I tire very easily and have been experiencing some headaches. I'll take that over tha pain I was in before.
I've found it's better to take in the evening because suroundings do become a little hazing sometimes, and I find it hard to concentrate at work, so I look for sites on the meds I am taking instead...
