Leslie, It sounds like you are losing patience and exhausted from months, if not years of pain. I am so sorry.
Dr MacDougall says to give it at least a 4 month trial, 100%, for autoimmune disease, and I know for myself that the improvements are really subtle over time, but they are there. Why not eat on the regular plan, without the eliminations, and see how that goes, then eliminate things more slowly? That might make it easier to give this diet a really good try over a long period of time.
Prednisone is awful, no doubt, but it might not be making your disease worse as quickly as you fear.I say this because I know how easy it is to feel guilty about taking medications, when trying to be in the best possible health, and I think we pain sufferers have enough to deal with, without adding extra guilt.
Look at
Caroline Duke's Star MacDOougaller story. She had psoriasis, an autoimmune disease, and is a nurse, I believe. She started eating this way for overall health, never expecting it to cure her psoriasis, (which can be extremely painful and disfiguring, and lead to psoriatic arthritis, too.) It took her years to heal from it, she never expected to, yet she did.
This diet is not entirely predictable when it comes to the more complex diseases (autoimmune disease, cancer, etc) that are related to diet but cause by multiple factors (genes, environment, exposures to toxins, overactive sympathetic nervous systems, etc.)
Our bodies apparently choose to heal at their own pace, and prioritize the healing in ways we may not want or expect. But given the opportunity to thrive, the cells will get rid of the extra wastes stored, and the fat will release the toxins stored in them, and changes will occur.
The point of eating this way is not just to stay off drugs, although that is a nice one. The point is OVERALL health, not just the relief from one aspect of health. And healing this way can take a long time. Looking at it that way kept me on the diet many times when I felt like it was all worthless.
We are all rooting for you!
