I don't have a bag but I have found stool softner to really help me.
That's great you figured it out. It's all trial and error.
I do very well with salad. But I had a really grainy whole grain bread with a sandwich the other day and was in a lot of pain. The doctor said I could eat normally now and eat whole grains, but I guess it was too much. I'm two months out from surgery.
Merry Christmas!
