Congrats on your fasting! As this is a Master Cleanse Forum
I'm wondering if you might find better info on a forum more specific to your type of fast. Can't answer you ? about your tongue on the 1st day either. Hopefully someone else can with more experience than me, as this is my first MC. Some of the people in this forum have A LOT more practice at fasting than I do...
Best Wishes for a healthy, productive fast!
