Hello. I was diagnosed with a bit of pneumonia 4 days ago and they gave me Levaquin (I think that s what the antibiotics is called). I had completely lost my voice and felt so bad. I am feeling a bit better but why do o feel so I mean so weak, tired and sleepy, again, even though, I m Taking my antibiotics and feel better than days ago. It s just the weakness, tired and sleepiness. Why? Gina
