No, I haven't tried the antibiotics yet. My new GI gave me a month supply of Align and I was hoping that I would get the same results from it that I got from Udo's Choice (I started Align on 2/11/08) last week was pretty good - had a normal BM almost every day, but this week I'm back to the days of C followed by days of D and constant gas. I think I'll do another round of Udo's choice b/c I really noticed improvement with it. If that doesn't work, then I'll consider an antibiotic. What I am finding is while Heather's diet does decrease the number of days/week that I have D, it really isn't improving my quality of life b/c I'm in a constant state of either C or D. I have to say that I do follow the diet very strictly (mostly just soluble fibers ,fish, chicken, turkey and applesauce). There is absolutely no UNSAFE foods in my diet, but yet I have constant problems - getting very tired of it.
Anyway, now that I got my pitty potty out of the way, I strongly urge you to try Udo's Choice for a month before doing the anti-biotic. But on the other hand, my daughter who's an RN thinks I'm nuts for not trying it.
I'm sorry, I can't be of more help. Please keep me posted.
