One of the things the program addresses is how people who struggle with IBS for a long time can actually start throwing roadblocks in front of themselves (often subsconsciously) to keep their bodies in the same pattern. I think it's a way people keep themselves from trying something new that might fail, thus leading to more disappointment.
But - at this point there is literally not one single reason for you to not accept the program as a gift, and do it. I've read through all the posts on this thread, and from an objective point of view all of the reasons given for why you haven't done or can't do the program come across as excuses. I think you're so beat down by IBS at this point that you're almost afraid to try yet one more thing - because what if it doesn't work?
Please accept the program you've been offered as a gift, and take a chance. The odds are so truly great that it WILL help, and you will not be disappointed. And the program will directly help stop the unconscious pattern of thought and behavior so that your body can change itself, and start functioning normally. It IS a change - and to me it actually sounds like you are fighting any change at all. But this would be a change for the better.
