If tongue is clear, is cleanse over? How do you know when to stop?

Hi, I am planning on going 30 days on the cleanse. I am at day 8. My tongue had a thick coating of white 3 days ago and since then, every daily small patches of white have disappeared, leaving the natural pink color. I figure at the rate the portions of white are leaving, my tongue should be completely pink within 15 days. Do I stop the cleanse after this, or is there more healing to do once the tongue is completely pink? I am interested in deep cellular healing, that is why I am going 30 days. But if my tongue is clear does that means that all is well and I can end sooner?

Thanks,
