You know I'm thinking the tongue is an indicator for some things but not an exact guage of cleansing. I was surprised, a little smug and a little skeptical that my tongue doesn't get very coated. I didn't get headaches but I'm thinking there's no way I'm next to clean/healthy, maybe healthier than average but not optimal health.
Well I was right because after 4 days of fasting energy had returned but I had a huge healing crisis and it was all about the mucus! I've spent the 5 days since blowing my nose and making the most horribly congested coughing noises you've ever heard and drinking vinegar/honey juice so my throat doesn't hurt so much I can't sleep! Just a warning, you might be right about that mucus.....
But it's good news - better out than in!!! :-D (feeling better now...)
