Often when one is going through die off or detox, their physical appearance can look wretched/haggard and dark circles are what I also get. I improved this by the candida diet however and it made it easier to detox other toxins.

As the toxins are now being moved around and out, it is hardly surprising that the symptoms have intensified. That is when you can also experience more allergic reactions as it's happening too. So you get a combination of reactions.

Healing symptoms are never easy to deal with. And they dont' usually make you look good either. I have often resembled somebody on strong drugs when I'm detoxing/healing.
