This is normal as explained by some LLMD's. You just killed most of the bacteria in your body. Your "toxified" , and prob need to detox better.
The debris will get out anyway possible, even through your skin. The remainder of bacteria is also fighting for a land grab- on your skin. It was there before, but balanced. The re-balancing takes time. I would suggest eliminating all milk products and possibly gluten at this time as well, because, for a while, your skin will be a teen again.
