I've had 2 UTI's this past year, and it was because i was too busy to drink much water. You need it to flush out your system in addition to external hygiene. I have been drinking water like crazy and have not had a bladder infection since. When you are taking pills and trying to get rid of the infection, you have to drink tons of water as well. Also, drink cranberry juice, it prevents bacteria from sticking to your vaginal walls.
