I think after doing a few MC's you're probably better off tweaking and experimenting, but it might be confusing to post such variations on the Master-Cleanse forum. But the Sucanat is almost not even a variation since Burroughs does recommend Sugar cane juice (albeit freshly squeezed).
I also don't do the laxative teas every day or the SWF. The laxative teas make me cramp and I don't think the SWF (Salt-Water-Flush) is necessary EVERY day.
Anyway, thanks for the info! I might try the Sucanat as a variation on a future Master-Cleanse to see what it's like.
