That sounds great! I'm sure you will see the other side of the mucous. The Master-Cleanse is such a powerful yet simple cleanse. I also became free of any mucous as a result of being on the cleanse during the first few days.
I wonder if you are exercising and also using a skin brush daily. I believe this would also help you a lot.
Keep us posted as you progress.
If you become uncomfortable take a hot bath and relax with a hot washcloth over your sinus area. Also diffuse some organic eucalptus, or add some to the bath.
Some body work like shiatsu would also be helpful!
