Unless you are taking things to slow the gut, I would be a bit concerned you have a partial obstruction, unless what you mean by "complete opposite" is that you are not having any problems. If you are feeling constipated, then you need to address it, as your stools should not be firm or too solid without a colon.

You could just be one of the lucky ones. Just make sure you are drinking enough fluids to keep things moving and eating enough food. Since you did not have IBD, you are probably going to adapt faster than those of us with UC.
