sinusitis
"I started taking Levaquin about 12 hours ago.  My muscles are very weak, I%u2019m dizzy, restless, didn%u2019t sleep last night, and having a very hard time focusing.  I%u2019m sure this is a great drug if you need to go to these extremes, but it%u2019s a little much for me.  I%u2019m calling the Doctor to get off of it this morning."
