The strange thing is I've been watching these Forums since November and I've noticed a few people that are prone to Psoriasis - get Psoriasis while MCing. (not when they b&p or parasite cleanse though) I just don't know! It seems that the Master-Cleanse exacerbates it or something. Wish I knew more about psoriasis, but I don't...sorry!
Since your tongue is nearly pink and you've done 11 days already, I think maybe end with a Liver Flush (toxins and Psoriasis are maybe related?) Also...the skin is ruled by the lungs....AH!...maybe your smoking IS related then!! (chinese medicine...the lungs affect the skin and the lungs rules Sadness and Grief - Any of that ring any bells?)
So, yep...I think you should stop the MC...and do an 3 or 4Day organic pear fast! I am serious! It is a super-detoxer and pears are especially good for the lungs!! I think you should try it. You can eat up to 10 pears a day (eat when hungry) and drink LOTS of water. I reeeeally have a hunch this could help. If you ever felt like quitting smoking it's good for that too.
Read the link below. Again..pears are specifically healing to the lungs...and I and friends of mine have had AMAZING results getting rid of bronchial infections just by eating lots of pears. It works!
So...that's my suggestion...segue from the Master-Cleanse into a pear fast....
*let us know what happens with the urine feet thingy! It looks like it reeeally works for that!*
