I'm an infrequent visitor to this board, but thought I would just share a current happening. As background, I've had IBS-C for 36 years, but of course was only diagnosed in the late '80's. I manage it with probiotics, exercise, water, Intestinew, MOM when it gets bad, sometimes lactulose, sometimes Miralax; enemas when it's really bad. You all know the drill. I am very aware of my disease and have tried a myriad number of products over the years, many of which didn't work after a while.Well, I needed a refill of the lactulose and called my GI's office. He had medically retired and the office never told me. My former GI was very good--he would always ask me what I was doing and if I had found any natural products to use. He took notes and would pass them on to his other patients.So, I made an appointment with his replacement GI doctor. Well, after waiting an hour and a half for the doctor (grr), he came in and said: have you considered using more fiber??? I couldn't believe that he said that to me. My former doctor knew and had it in my file that too much fiber caused me more problems--got all clogged up. Then he said that I needed a colonoscopy.I did liquid diet for a day and then that evening drank the bottle of Halflytly. I thought that my last BM was clear after being up all night. So, they put me under to do the colonoscopy. Next thing I know, I was in Recovery and the nurse said he couldn't do the test and that my prep didn't clean me out good enough.The doctor came in and said the same thing. Then he asked if I had followed the liquid diet and then drank the jug of fluid. Yes, I said. Then he asked me if I had the big jug or the little jug. I said the little jug and I added that I had had the big jug in the past. He said to me: "Why didn't you tell me???" I had had a colonoscopy 8 years ago--I didn't know if the test prep had changed or whatever. This really got me mad. Then he said, we need to do this again (this test was on Friday and he wanted to do it again on Monday), only this time, do 2 days of liquid diet and the large bottle of liquid and a Citrate of magnesia. I was ready to leave with my husband and was really looking forward to breakfast. The nurse heard me and said, oh, no, you can't eat till after the test on Monday. That would have been 4 days without solid food. I canceled the test and rescheduled it for this Wednesday. Today is my first day of liquid diet. I'm so perturbed by the whole thing.Has this ever happened to any of you?
