Darn! I was afraid you were going to say you had issues with dairy and/or eggs. Okay, go for liver!
Re: the mucous and such. Not all mucous is bad! In fact, it is the protective layer of the intestines and without we cannot absorb foods or allow friendly microbes to live and protect us from bad microbes before they enter the bloodstream. It is only when cleansing that we refrain from mucous-forming foods (well, almost always refrain from pasteurized/homogonized dairy really) because we need to shed the toxins that get trapped in it. Once we're done shedding mucous and toxins, it's time to rebuild the healthy mucosa lining.
How abuot goats milk? Maybe you can find pastuerized but not homogonized, that would make a good kefir, and from that you can make fantastic lassi.
During meals try NOT to drink, only a cup or two of green or herbal tea or digestive lassi is okay.
You're going to need lots of protein. So long as you keep taking digestive enzymes you should be okay, you just have to find a protein source that works for you. Chances are it's best for you to start out with homemade broths, as they are very easy assimilated. Try making the Kichadi recipe with chicken broth, perhaps.
In order to recover fully, you do need your colon to actually do some work and pass BMs. So it would be best to keep up on fiber (freshly ground flax seeds preferably, plus eat Kichadi and blueberries, raisins, dates, figs, almonds), a cup of fennal tea about 3-4 times a week, and an enema only 3x a week. That way you will be exercising your colon yet keeping it clean enough to keep your symptoms reduced! :) Make sense?
You can make one of your enemas each week a probiotic enema by adding kefir to it.
