Dunnyrunner - I surely "hope" you do have the Caltrate where you live! It works wonders for the diarrhea - I can attest to that! And I haven't needed any other product in addition to the Caltrate either - except Lactaid for my milk intolerance! Myself, I wouldn't want to use the Immodium - I feel comfortable using the Caltrate and it works for so many people here. If I were you, I would really check into whether or not you can purchase it there...Good luck.. and you are right, I feel the same way, just go and do things - can't let the IBS hold us down! If you try the Caltrate, you may never have to worry again...!
