I completely cut gluten out of my diet and try to stay away from foods that are known bladder irritants and it is much improved. Try to cut out chocolate, citrus, alcohol, and DEFINITELY tomatoes. It takes a while for your system to completely get rid of all remnants of these foods in your system but wait it out its worth it! Good luck I hope this helps some people. I am blood type O positive for those of you out there who may be following the blood type diet.
