When we do CE's, the action of the Coffee-Enema doesn't change...however the condition of our liver (and the rest of our body) changes daily.
It's very common to get vast amounts of relief initially when doing CE's (especially in the presence of adrenal issues - because adrenal stress causes all organs of detoxification to work less effectively). When our adrenals are stressed, we can be stuck in "flight or fight". If our body (chemically) is in the state of running from a charging rhino, it's not that interested in detoxifying our bloodstream (or assimilating nutrition, or fighting pathogens, etc).
So you got a LOT of relief and felt much better when you first started the CE's...but now your body/liver does not have the 'serious desperate need' for the CE's as it did before - so you don't experience the same serious relief. That doesn't mean you should stop them. But it does mean that you likely need to do some more cleansing (and likely support your adrenals more fully).
Epsom SaltLiver Flushing will likely get you into trouble (ES is extremely harsh on the kidneys/adrenals). Dr. Schulze flushed thousands of livers safely and effectively without the use of ES. Water already linked you to that FAQ.
If you started the CE's around the time you started the IF#1/IF#2, and now you've stopped the IF#2 - that could be another reason why you're not feeling as good.
I don't suggest juice-fasting or primarily juicing without the use of IF#2 (or the addition of activated charcoal). That's because when we juice-fast or cut down our solid foods substantially, the body starts throwing off the poisons/toxins that are embedded in our tissue, fat & bones...and this is stressful for the liver, kidneys (hence the adrenals). So if you taking IF#2 (that has Bentonite & charcoal) and stopped taking it, I suggest restarting it...or adding a minimum of several teaspoons of activated charcoal to your diet daily (spread throughout the day).
And if you add our Adrenal Tincture, that would be even 'more better' for your Adrenals (it's Dr. Christopher's formula, and your adrenals will love you for it :)
So, I suggest continuing the CE's (normal CE's); adding IF#2 or activated charcoal; adding Ashwagandha and/or Adrenal Formula tincture...and continuing with Liver Cleansing and kidney cleansing (using Dr. Schulze s method and herbs for liver & kidney work that you can read about in the FAQ).
'Sounds like you're doing good work...I'd bet that your body is just detoxing a little faster than your adrenals appreciate - and you'll feel a LOT better when you give them some additional TLC :)
