Yes, IE, that's the way Michel Gingras did it during his 2 long water fasts....one in 2007 (21 days), and the other in 2009 (26 days). I guess I want to be more structured than that. But he did experience good results. Have you seen him? He's at YogaYak.com.
Any other ideas? I'm considering breaking with Celery juice, rather than with the typical Orange juice. However, for only 6-days, solids could probably be taken.
