bronchitis
"I've been taking Levofloxacin for bronchitis (5 days, 750 mg), and I think it's helped a little bit, but it's day five (last dose tonight) and I still feel only a little better than I did before I started. Maybe it's a virus or something, so it isn't responding? Oh well.

The biggest problem I've had is the side effects: not as bad as what most people have been talking about (knock on wood), but I have experienced severe, severe nausea, and also insomnia. I take it at around 6 p.m., and the nausea usually goes away by the next afternoon. I started taking it with food, and also drinking a probiotic, and it seems to be helping a little, though I still feel a bit sick. 
The insomnia is pretty bad! "
