I would say that is not normal, but maybe adding in some flax meal to your menu would be helpful, it is good to add to your morning cereal make muffins with or add to yogurt.. If nothing works you should see your dr about it... Or at least I would...

Hi there! Are you on any certain medications that could be causing this. I know that I am on some pain meds including morphine and sometimes this happens, their are times that I have to use m.O.M. Or magnesium citrate as I do realize not going can be just as bad as going too much but I am not a dr or am I recommending this to you. My suggestion is to you is that you might want to talk to your dr about this as their might be a medical problem and might even want to do a colonoscopy on you. Also, look at your diet, are you eating enough fruits and veg. And bran.
Good luck to you and let us know what you find out!
