Along with this, don't forget about
the water. Keep it going in you. It helps with matters of coming out. And walk if you can. Even if you can't walk much. The cascara sagrada is a very good natural way to stimulate. And the stool softener is a very good idea.
Good luck...
Sorry ya have to have surgery. My stepson had two on his back, metal rods put in. He said that the second surgery made him feel better than ever.
I hope all goes well.
The metamucal should work good for fiber intake...
