You might consider adding Docusate Sodium/Sennosides to your daily medication regimen. It's over the counter and one brand name is Senokot-S. 1 tablet 2 times daily usually works but you may take up to 4 tablets 2 times daily. Adding one tablet every day until relief and then staying at that dose is a pretty standard protocol. This combination medication both increases bowel motility and softens stool.

Good luck.
