sinusitis
"I have taken Levaquin many times for my sinuses and have had 2 sinus surgeries.  I am currently on my 38th day of 750mg and have 11 more days to go of taking it.  We are doing this for so long as a last resort before doing surgery again.  I can not tell that it is doing much good this go around.  It does not allow me to rest well so I take it in the morning but  I can honestly say that I am over the vomiting daily because of it.  It also gives me the shakes and just a very bad overall feeling until lunch or so."
