I agree with a few people here, that it would still be a great accomplishment to do 30 days, but from the sound of what you're writing it's a good chance you'd regret giving it up early.
Still, you didn't go raw the first time you trialled. How about giving yourself a Christmas present and doing 46 days - giving yourself enough time to transition back for a raw christmas at least.
Growing up as the only vegetarian in a family of meat eaters, and now in a relationship with another one, I know exactly what you're feeling. It's going to be enough of a challenge doing a Christmas staying raw, I think, without adding juice feasting into it. You might want to make it a family decision.
I reckon the full version of this trial would be perfectly suited to over 'Lent' - there's an acceptance that it's a period people will be depriving themselves in some way, so the isolation might not be so bad then...
