@jackiem95 I can certainly sympathize with your problem as I've had three surgeries of the upper digestive tract and I'm always trying to figure out a diet that will work to keep my system regulated, but not work so well as to cause diarrhea. You mentioned Miralax and referred to it as a "heavy duty laxative" however, it is not a laxative but a stool softener. Have you ever tried it? There are other stool softeners like Colace (that is the brand name but it is available as a generic) It does take a few days of treatment before you notice a difference.

A balanced diet is always important as well as exercises, especially after eating. Stretches and bending at the waist, walking, etc. can also be good ways to prevent and/or treat constipation. Also, drinking lots of water is important as well. I have heard of some members who do self-massage on the abdomen, massaging in a clock-wise manner.

I suppose, as @colleenyoung said, you have to keep working to find the right balance that will work for you.

Have you tried mild exercises after eating?
