Since I started the Renew Life Liver Cleanse and began liver flushing, I have not experienced the neck and shoulder stiffness.
I have also noticed that breathing through my nose seems much clearer, although I did not notice that it was poor before, only that it seems much easier to breathe through my nose.
I`m having issues with my lungs and asthma though, not sure why. That acts up once in a while.
