Hello everyone...I guess I am new to the group and I wanted to know where you are all from. I live in Toronto, I'm 20 and I have had IBS forever. My Dad has Colitis but the doctors say I don't have it.I have been reading your page for the last couple of weeks just trying to find information on IBS. I was only diagnosed last year and have not yet gone to see a specialist. I saw that a lot of you recommend Caltrate. How does it actually work? Does anyone know?
