Had ate the normal calcium and vitamin tabs last Sunday (Checked the expiry date and not had them for the first time), and loose motion started and has not stopped yet. No stomach ache but shivering and constant loose motion, around 3 times an hour. Took sporlac, 4 tabs-twice a day but no better results. Think it might be the cold but not sure how to go ahead with it. Also a little bit of dry cough.
