Levaquin and talking in my sleep

During the first 4 days of Levoquin for treatment of pneumonia started feeling very tired with some aching muscles. It continued to worsen until it became severe pain in my joints (especially hips, knees, shoulders,elbows and hands). I became unable to rise from a sitting to standing position; someone had to lift me up, still with excruciating pain in knee joints. Also had nightmares and started talking in my sleep. Refused to take any more and MD ordered a Z-pack which I am just starting. What an awful drug Levoquin is!!!!!!!
