I guess it is that everyone is different. The same thing you hear all the time. Bran does work for me and it is the only thing that will work. I don't eat the Bran Buds daily because I hate the darn taste, but if I am really blocked I eat that for awhile and I go every day. So, if something works for you, then why not stick with it.
I always add something else to my breakfast since the cereal is only 1/4 a cup. I cannot do oatmeal. I bloat up like a balloon. It took me some time to figure out that the oatmeal was the problem.
Bran Buds does not bloat me or cause me grief, so I continue to use them. HTH
