Hi,I too have IBS and recently passed my first kidney stone. I was blessed that it only hurt for a few minutes and I passed it, but I knew as soon as I felt that pain in my back that something was wrong. I found on a website for kidney stones that taking certian supplements can decrease your chances of having another one by 80%. It depends on what kind of stone your passing though. I would have them test the stone to find out what kind it is, and then ask your doctor about vitamin b-complex, magnesium citrate, and potassiam. If you have the common kind then these supplements might give you a break from having them so often. My family has a long history of kidney stones. My grandmother lost a kidney to one, so I can relate with you not wanting to have them. To me the pain is worse than labor! Good luck and God bless.Cyndi
