When they put you on antibiotics, you HAVE to finish the whole course, because even if the symptoms go away, the cause could still be there, and stopping the antibiotics early could let it linger in your system, and develop an antibiotic resistence. So this time, make sure you mention what was prescribed last time, and between now drink lots of water - that helps, I've been told.

I haven't had a UTI for a long time, but man, they are NO fun.
