Using all those supplements and stirring up toxins, your quest will be so much more successful if you do enemas as well. You can order an enema kit online at www.healthandyoga.com for a good price. Don't forget to order extra catheters. You can do an acv or acidophilous enema everyday if you feel you need it (I did four days in a row) there's good info about that on here as well. And a coffee enema at least once a week. That really helps to take the toxins from your liver. As I've found for me they are very dehydrating, try a plain water or acv enema after and drink lots of water.
You didn't mention anything about healthy oils, which are so important for healthy skin, you want an omega 3-6-9, take at least 6 a day. Also zinc 3x's a day and I've found after taking L-Cysteine which you mentioned and L-glutamine which work together for only a week I can definately notice a difference.
