Got an RX for this yesterday. I have taken a total of 2 pills (100mg dose). I have had an awful headache since the first dose, nausea and now my neck hurts a lot. Also first dose made me very drowsy and slightly dizzy, napped for 4 hours after first dose. Not taking another one of these ever again. Would rather have the UTI. Hope they can give me something that isn't awful. Why would they even prescribe this? Lucky I found this site because I thought maybe it was just me overreacting
