ms.ellisI know just what you are feeling. You need to try taking the caltrate plus calcium supplement in the white and purple box. Take one with each meal and you will feel relief from the first day. It is pretty amazing. If I can answer your questions email me. LNAPE###AOL.COMAlso check out the ibsgroup.org borad for lots of info on calcium and how it is helping. Check the post your calcium story I would like to hear.Linda
