Thanks for the response. I appreciate any help....although we have a long history of lactose intolerance on my mother's side of the family. I have known I have that since I was around 14 and I have cut out milk, cream in any form, even cream soup & ice cream, cheese, etc. That is why I am trying only a 1/2 carton of Activa at a time, morning & evening. Even yogurt bothers me. So I don't think dairy is the problem because I am very careful with that. I was diagnosed with IBS after extensive testing back in my early 20's when they could find nothing really wrong. I will be going through it all again soon. I take a lot of vitamins. I have read about
magnesium causing problems and calcium carbonate helping. I am a long time calciumcarbonate taker but mixed with multi vitamins and many other vitamins. Right now, I am cutting all out for a while and then I plan to try the Caltrate 600 Purple. See what that does? I hope there is someone out there that may have the answer or help with the gas problem????
