I think what you mean is that you don't want a stimulant laxative. Those things are horrific. I accidentally took too many and RAN to the bathroom. It was a close call.

However, you could try Miralax for a week or two which is non-stimulant. It is a polymer in your system and really bulks up in your colon. It seems to do something similar to psyllium fiber. So Miralax is another good option if the fiber 3x daily doesn't work.

And of course there are other options like yoga, walking, abdominal massage (I like to do this sometimes, gets things moving).

Good luck with all this. Constipations sucks!
