1) I have to be at work at 6am--how should I use the SWF/lax tea?

You should drink the lax tea at night, and again in the morning if you are unable to do the swf, which it sounds like you probably can't. The SWF (Salt-Water-Flush) takes about an hour to pass through and can be quite dramatic (definitely not for the commute!), so you may wish to stick to the tea on weekdays, and reserve the swf for weekends. I posted an easier way to drink the swf above if you are interested.

It is not part of the Master-Cleanse protocol, but I have done a lot of fasting and often substitute a plain water enema for the tea/and/or swf as it is convenient and gives me control over when and where I cleanse my colon. It IS critical to do a colon cleansing routine every fasting day to avoid detox crises! And should a crisis arise, many times I have had a plain water enema stop it dead in its tracks. A handy tool for body cleansers.

2) Will I be able to exercise?

Absolutely! Barring detox crises, or days when you feel low, you should be able to do everything you normally do. I have fasted up to 60 days and exercised every day barring low spots, and felt great! If you are a heavy exerciser, you may wish to stick to a moderate routine. Also, I like to dissolve 1 T. BLACKSTRAP molasses (recommended for diabetics/hypoglycemics doing the MC) prior to a workout for a great lift! You can take it plain with lemonade, too. Be sure to drink lots of extra water every day you fast!

3) Is green tea/decaf herbal tea allowed during the cleanse?

Green tea probably would be best left for post-fast. However, I have often used mint, chamomile and rose hip teas, particularly during crisis times when I felt flu-ish, and some folks swear by mint tea to help freshen their mouth.

Have a wonderful cleanse!

Best,
