Just had to share with you all that Caltrate has helped me in ways that I could not have imagined! I feel like a NORMAL person again and I really owe it all to Linda and her informative post. I have been taking 1/2 a pill 3x a day and after the 1st dose I have only had one D attack (due to my own overindulgence) and I feel great. No longer scared to go places and I even went to a concert and enjoyed myself. Just had to share and hope that many more people in the future find relief from this simple remedy. Thank you so much Linda you have given me my life back!! I could never thank you enough!! I am telling everyone I know that has IBS to run to the store and get Caltrate.
