I have been taking Levaquin 500 for bronchitis for 6 days. The first 3 days were fine. On the 4th day when I woke up the room was spinning. I went back to sleep for a while , thinking that if I did when I woke up, the spinning would have stopped but it didn't. From there came the nauseousness followed by headache and eye pain. I had no energy but could not lay down because of the spinning. For the rest of the day, I just felt bad, physically and mentally. I started crying for no reason. The next day was much of the same and I started thinking that this must be the medicine so I checked the internet for the side effects of this drug. My symptoms sound like I might have gotten off easier than some but guess what I am not taking that last pill.
