I would say that it would depend on what your goals are. You seem to be having an easy time of it same as me and I'm on day 26 and will continue as long as it doesn't interfere with my schedule and commitments till I reach 40 days. This is my 4th MC I have done 40-28-21.
I do miss the social aspects of things a bit cause so much revolves around food and drinks but I have attended several gatherings and have gone on 2 day camping trip with my trusty lemonade in my Nalgene bottles and no prob. I just got myself a glass with some ice poured my lemonade in and sipped on that.
My friends have seen my transformation from when I started on the cleansing trail a little over 3 years ago so there's little flack, not that it would bother me and as a matter of fact several have gone on to do the MC themselves inspired by my success.
