I agree with Somer. You are going through a cycle of cleansing, and you most certainly do not stop on a low, so by Thursday you will have probably have come back up. If you want to really see the improvement of your tongue, you can look up the different areas on it to see what organs they correspond with, and then you will have an idea of what parts of the body are detoxing. Also, get a tongue scraper and you can actually see the patterns of the detox going on a lot easier. Ideally you want your whole tongue to go pink. Molasses is a great alternative to revive your energy too!
