I would not take the fish oil or milk thistle during the cleanse because it will just be flushed away through the detox…so you are mostly throwing it away. These are great supplements to take while on the diet but not the cleanse.
The skin problems you are experiencing is from the “die off” toxins from the dead candida. The body detoxes in a few ways; via the skin, via the lungs, and via the bowels…so right now it is detoxing via the skin because possibly one of your organs are too taxed. Its a pretty normal symptom that most people experience when trying out the diet. It should improve in time; taking a sauna, hot tub, steam room, jacuzzi, or even hot bath can help improve your skin and help you detox the toxins.
I would also get some molybdenum which can aid in the die-off.
Check out the protocol in the meantime:
