I looked at the post op instructions from my CRS and it says to eat a normal diet, but not to change it to cause too hard or too loose stools. Only psyllium husk is recommended, no softeners or laxatives. Only if your stools are hard right after surgery, because many people have a hard time with the first BM and can't go for a few days they recommend temporary use of colace or milk of magnesia. He explained if you don't get the muscles used to be stretched in a gentle way with the bulking but softening properly of the husk, then every time your stool turns a little hard or bulky you will be back to square one.
My advice missy is to simply give it a try.
