Sorry to hear you're suffering from this so...I went 6 months with constipation, and tried the fiber/bulk stuff...my neuro told me absolutely stop the bulking agents!! He told me eat the fruits/veggies and nuts...esp almonds, every day. Beans, etc. And finally, after listening to the guy, I went and haven't had constipation for about 4 months. I do suffer from IBS, so I have to watch the beans/salads...

I can't think of anything else besides all you're doing...I do know the zanaflex is a muscle relaxant, and I take a lot of it...it relaxes the intestines as well

Let us know how you're doing and if you get any other answers...and relief
