Lc, I was turned on to a simple daily dose of cream-of-tartar (the stuff that you put in egg whites to whip and make them fluffy). 1/4 teaspoon cream-of-tartar + 8 ounces hot water. The water should be at least near boiling to disolve the cream-of-tartar. Let it cool then drink. You can use more cream-of-tartar if needed. It works the same way as cranberry juice by acidifying the bladder, but is much more effective and no sugar. It just tastes sour, kinda like lemon juice. I do have an indwelling catheter, being a C5 quad and have had NO uti's in 2 years!
