Hi Nelson.wonder if u know how to prevent the coomon cold from happening.this has become a huge problem for me.it only takes me about two hours of outdoor night california air to be totally jammed in the nose and i can barely breathe for the next few days.3 years of cycling juice seems to have done this to me.this problem only started since december.i've tries massive doses of echinacea and vitamin c and it did'nt help at all.any input will be appreciated.thanks
