Dear Harrowby,
No, just that it is in its early stages of research, more complicated than just replacing one set of bacteria with another, anyway the reason I started this little thread was all about diet drinks ( which I dislike ) the Doctor who was talking about fizzy diet drinks says that our bodies, our minds are conditioned to expect sugar, when the body does not receive the sugar you are left with sugar craving which doesn't help anyone dieting.
