In the meantime, until you resolve the question of why you are suffering from such serious constipation, if you don't already have an enema bag, I encourage you to purchase one and use it whenever you feel uncomfortable and need relief.
You can buy an enema bag at your local pharmacy, or order one online at http://www.enemabag.com/
Also see my website at http://valerie_cct.tripod.com/enemas.html on how to give yourself a safe, effective, and comfortable enema.
