Some things to consider(some previously posted):
You may only receive 10%(arbitrary number) of the benefits from the juice feast in the first month, who knows what you may miss from the other stages(especially after the liver cleanse, etc)...
This may be a great opportunity to learn new ways to connect with your family
Potentially many(thousands?) people who may derive more benefit from juice feasting(people that are currently very unhealthy) may be dissuaded from juice feasting - "if Steve Pavlina couldn't even handle it, then how in the world could I???"
You set out to reach "a whole new level" in your life, permanently. You may find yourself wondering if you missed out on that level later on, if you stopped now.
You may have come further than you think, mentally. You may return to eating raw only to find that you seem to feel a bit mentally "fuzzy" or something, compared to how you've been feeling lately with your "slight gains"
Thanksgiving and Christmas do only come once a year, but they also come EVERY year. Besides you'll still have your Thanksgiving "Feast"
It may be helpful to go back and read some of your earlier posts about juice feasting for yourself to see if they reignite any of the passion for juice feasting you were feeling when you wrote them
....Obviously, I'd like to see you continue, but ultimately, follow your intuition. And go with the flow. If you're heading in the direction of the greatest good, the universe should come to your assistance.
Good luck, peace, and clarity...
