Jeannine,
We each have various posts scattered through the archives, roughly describing how we went about our treatment programs, but I'm not sure that any of them are very comprehensive. In my own case, I was extremely disorganized, and I was sick off and on for a couple of years before the D started and wouldn't stop, and I finally decided to face up to the problem, and go to see a doctor about it. My doctor decided that I had cancer, so he sent me to a GI doc who agreed, and I was given every test he thought was appropriate, but he never found anything wrong with me. After that, I floundered around for about a year and a half, before figuring out how to achieve remission. Because of all the time wasted trying to find a solution, and years of unnecessary suffering, and even some permanent damage to my GI system, plus the fact that my GI doc was no help at all, I felt a need to try to help others who might find themselves in the same dilemma, in order to shorten their path to remission. I can't speak for Polly, but I'm pretty sure that she feels the same way. I believe that she was much better organized, in her journey back to good health.
Basically, after doing a lot of research, I decided that I must be a celiac, so I cut out gluten. I started keeping a food diary, including reactions, and notes on how I felt, a few weeks before I started the GF diet, and after that didn't bring remission in a month or so, I started "testing" other foods. After a year, I seemed to be a little better, but I kept getting sick. It took me another six months to get my act together. Here's a quote from an old post, that discusses this:
I remember after I first cut out gluten, I was keeping a diary, and I could see that dairy products and corn, were causing problems, (among other things, such as fruit, nuts, sugar, and some veggies, especially lettuce), sooooo about every two or three weeks, I couldn't resist "testing" myself, to see if my gut was "healed" well enough to begin eating them again. Consequently, every two or three weeks, I got sick again. LOL.
I wasn't a big fan of the other intolerances anyway, so I never tried them, and at the time, my best guess was that I might be a celiac, so I wasn't about to eat any gluten, but I had read that any type of enteritis can cause temporary lactose intolerance, so I incorrectly assumed that my dairy problem was due to lactose intolerance, and therefore it should be temporary. At the time, I couldn't find any references to corn intolerances, (only corn allergies), so I assumed that it was temporary, also, and I hadn't run across any discussion boards that made any sense to me, since I didn't really know what I had, anyway, (I couldn't find any celiacs talking about corn intolerances).
Anyway, I finally figured out that it was the casein that was causing the problem, so I quit testing myself, and things went much better after that. LOL.
The thing about food testing, though, if you're taking a med, is that meds change the way that we respond to them. Without meds, it's pretty straightforward. The consensus of opinion on this board, in the past, (among those of us using diet alone, to control our symptoms), has been that remission can always be achieved by diet alone. We've had so many tough cases to come along lately, though, that now, that position has been called into question. Deep down, I still believe that diet alone can do the job. The problem is, if there is one single confounding element in the diet, then the whole effort is a lost cause. Stories like the one that Carey posted, about coffee laced with corn, for example, illustrate how easy it can be to be "stumped" by a diet, even though you might be doing everything right.
Unfortunately, I didn't find an MC discussion and support board, until after I was in remission, (because I didn't know what I had - you can't find MC, unless you know what you're looking for, and that applies to information and support, also). Anyway, a few months later, I stumbled across the old board, where Polly and the other "pioneers" met every day, and I thought, "WOW!" These people are all just like me. When I first joined, I thought that I was just wasting my time, because I was already in remission. I soon found that I learned more there, every week, than I had learned in a year of researching, on my own. Their support, compassion, and understanding, was truly empowering, for someone who had been "lost in the wilderness" for so long. Finding this group of wonderful people was surely the best day of my life.
To answer your question about diet details, I cut out gluten, for about a year and a half, and then I also cut out all sources of dairy, corn, all but small amounts of all types of sugar, all fruit, all vegetables, (except for squash, an occasion serving of green beans, and broccoli - broccoli causes gas, though), all nuts, and all sources of soy. As soon as I made that step, I was in remission within a couple of weeks. For approximately two years, I lived on meat, (mostly pork and poultry, because I reacted to beef), potatoes, rice, those three vegetables mentioned, and I drank water and unsweetened tea. Every time I experimented with anything else, I ended up getting sick, so I stopped experimenting, and allowed my gut to heal. After that, I was able to slowly introduce foods back into my diet, starting with small "doses", and slowly working up, and now I can eat virtually anything, (except gluten, of course). Beef and peanuts still cause me to have gas, bloating, a few aches and pains, and a generally cruddy feeling for about a half day or so, (just as they always did, while I was healing), but they don't cause D - they never did before, either.
I am fortunate, in that the foods that I had to cut out of my diet were apparently "irritants", and not "intolerances". Most of us are not that lucky. If you do tests at Enterolab, and they come back positive, then you will probably never be able to eat those foods again, without reacting - except for yeast. It appears that we are only yeast intolerant when we actually have a yeast overgrowth. My tests were all negative, except for evidence of gluten intolerance, and sure enough, I am now able to eat those foods again.
Remember that we are all different, and everyone has to fine their own diet selections, (or else cut out all possible intolerances, and experiment with reintroducing them, after acquiring remission.
Best of luck with your program, and please keep us posted on your progress.
