Mine FINALLY turned cute and pink around day 27 of my 60 day odyssey -- after having done a couple very long (27, 40) day fasts prior.
Personally I don't put much store in that pink tongue thing. I definitely wasn't done when it showed up!
But it WAS cute...
You've done an awesome thing! I'm sure you have your break all planned out; of course a longer fast means a longer break. I was actually still eating break diet for 6 months after the 60 days!!
