Is drinking sprite, 7-up okay for kidney stones given the citric acid content in them?

NOT OKAY!!! I don't think drinking soft drinks is ok for anyone! they have extremely high levels of sugar (esp. High fructose corn syrup) and if "diet" forms then have nutrasweet, which is even more toxic. Anyone who has any interest in being healthy should hardly ever drink this poison! and yes, the acidity worsens risk of kidney stones. See http://texasfarmersmarket.Org/the-hazards-of-drinking-soda/.
