Urinary Tract Infection - have chronic uti just drinking lots of water how long til it gets better?

I even go as far as always washing my hands before using the bathroom. Idk if it's OCD, but I feel that our hands are always exposed to germs and not washing your hands before using the bathroom and then wiping yourself with toilet paper you touched with unclean hands is not good lol... Anyways, I was drinking water and cranberry juice too. I went to the doctor and surely I had a UTI. I was given some meds, which helped. However, I have been struggling with UTI's off and on since then with not much success from meds. I read cranberry supplements work and vitamin c supplements too because they help make the urine more acidic, makes the walls of your bladder more slippery and prevents bacteria from sticking. I had a recent UTI almost two weeks ago, and a friend of mine told me to drink orange juice because it would make my urine more acidic. So along with the orange juice, I drank water, I was taking cystex, and a few cups of cranberry juice and it worked! I won't say to substitute it for a doctor's prescription, but to help prevent those horrible UTI's or an "in the meantime till I go see a doctor" method. I've been doing that and I can say it helped. I honestly think it was more the orange juice because I'm not a fan of it and normally stay away from it, but man was I gulping it down more than anything else, and I felt more relief than when I was only drinking cranberry juice. If you try it, I hope and pray it works for you too!!!
