My wife now knows not to insist on pure cranberry juice, but rather to request a 100% juice blend and not “cocktail” (the cocktail is what the juice blend goes in). I finished the battery acid myself over the course of a few weeks, out of pure Floridaman cussedness. It was not pleasant.
My wife also swears by it, but I’m curious if objective testing might reveal if it’s actually relieving pain, or if the act of drinking this stuff is temporarily raising one’s pain tolerance to the degree that the UTI pain doesn’t seem so bad.
