Do you take 3 tablespoons a day of ashwaganda? I find that taking this along with Uny's adrenal tincture is very helpful for my fatigued adrenals. It(Uny's tincture) contains eleuthro but other herbs which are supportive to the adrenals as well. There may be something in the source that you used, and you don't mention if it was a tincture. Your sensitivities may be liver related, which you probably suspect since you want to do a liver cleanse. In the meantime you could put castor oil compresses over the liver, and you can start doing coffee enemas to cleanse and heal the liver. Were you using Uny's or Shulze's herbs for the KF? If not, there may be some problem related to what you were using.
Have you tried hot/cold showers? I find these help my energy a lot. When you are finished you are bound to feel a little better for a few hours, then you can do another one.
How are you eating, juicing, etc.?
How about bowel movemnents? 3 a day? and if not are you taking IF#1? How much water do you drink each day and is it distilled or reverse osmosis?
