Ciprofloxacin
"These are magic pills. I've had my share of urinary tract infections over the years. Ciprofloxacin works for me. After taking the first pill, I feel 80% better (usually in 3-4) hours. The second pill has me at 85% better. I finish the entire dose and drink it with lots of juice. I hate water, so unfortunately telling me to drink more water is useless. 
Here's some random information I've picked up over the years (based on my experience); You can drink alcohol, although I wait til on my last day of pills.
You can have sex once you start feeling better. Make sure you use the bathroom before AND after sex. No exceptions! You can sleep soundly after you've cleansed your bladder.
Don't wear thongs/g-strings so much.
Drink cranberry juice."
