I have not seen or used freelax myself, but it looks very similar to a neck massage machine someone gave me once. I would not have bought it myself, but I did try it, since I had lots of neck pain issues. While it had some benefit, the machine had limited capacity to really address my needs. I would expect (as Karen stated) the freelax would prove to be the same.
The concept seems very similar to a self-administered Chi Gong massage technique specifically developed to aid bowel movement (Chi Gong is an ancient Chinese healing system, one of a diverse collection of practices I use to keep things moving). I would learn that technique at the very least, or go to a professional as Karen suggested, (too bad the professional could set up shop in your bathroom every morning). I presonally would not spend money on the machine.
Yoga style rotational stretches are another way to "massage" the abdomin and encourge movement.
Hopefully, despite your CI, you still have the peristalsis of the small intestine to ensure movement. If you do, I would focus on protecting that. It is the rythmic movement of the bowels, as opposed to the singular "urge" that should empty the colon.
If your stool is soft enough and properly lubricated (with oils), the peristalsis will eventually push it out. You don't get that satisfying feeling of complete elimination every time, but at least things are moving (and I am not talking about diarhea).
Of course as you know (because you told elsewhere on the forum), diet is a key factor. I have shifted from eating a "healthy diet" to eating what is good for me. My best simplest suggestion is to check out Ayurvedic medicine. It's another ancient system of medicine (Indian this time)looks at the health of your whole body beginining with, of all things, your digestive system. But it also doesn't group everyone in to one type. It's done wonders for me, especially eliminating my irritable bowel syndrom and giving me more consistant stool. I have only just begun addressing my inertia issues, and as I shared elsewhere, my rectal prolaspe needs to be dealt with in the process.
Good luck to you and everyone with the healing paths you choose. Its great to have the opportunity to learn and share from those that experience it.
