I think form reading this forum most people seem to be the other way to be honest! But when I used the LL water falvourings and started having bars I got the hocolate waterfall , and it was verging on incontinance I will tell you!
All I can say is that my T H 's seem to have settled down now to going every other day and only the occasional bout of the runs. Maybe your body is trying to adjust, and it will get better , but if you are suing the water flavouring or bars , cut them out and see if that helps becuase they do contain inulin which will give you the runs.
Remember to drink more water if you are suffering from diareah because you may get dehydrated (I know seems impossible with 4 litres a day ).
Good luck and talk to youur LLC about it she may be able to help.
