Carter yes it is the healing of the gut to look at first so that food molecules are not getting into the bloodstream and most intolerances are hidden and even if you give them up it takes time for the gut to heal. Catseye knows a lot about this. Her advice is excellent. One thing I have found out is that the body wants to heal at its own pace and it does no good to try to speed it up. And each supplement and protocol must be introduced carefully and when the time is right. And agreed the process is slow if it at the speed the body dictates though it can be speeded up. I think your analogy of debt is good and agree that cfs is a symptom of the whole organism crashing.
