Help!! Uti problem!

Ever since I was 15 or so I've had really bad uti problems. I go to the doctor, they give me antibiotics, but it comes back a couple months later. I'm up every night constantly trying to go pee but nothing works for me. I'm losing sleep all the time, feeling exhausted at work, please help! What are some home remedies you ladies have used that help the stomach pains go away. I drink lots of water but that doesn't help.
