I really don't know anything about the Ultimate Fast but I can answer your other two questions. Yes, you can heat up the lemon drink and no, I would not recommend taking any kind of supplements at all with this - the lemon and maple syrup supply you with everything you need.

Hi, Here is where you can read the whole book online or even print it. At
http://www.healthandlight.com/TheMasterCleanse.pdf

in my opinion The Master Cleanse and the ultimate fast are two completely different cleanses. if you're regular, meaning you have at least 2 bowel movements a day, then i would go with the master cleanse, but if you're a little behind then i would recommended doing the ultimate fast, and then Master-Cleanse later down the road. the ultimate fast is simply an advanced colon cleanse, but because you are ingesting Bentonite and psyllium it does put unwanted stress on your digestive organs therefore it inhibits the rest of your body from cleansing as is triggered by MC. the idea behind Master-Cleanse is that the energy saved from digestion reverts to body cleansing and repairing. and you will need to reach a certain number of days before the body goes into this healing mode, which is usually around 7 days. as for supplements goes, as long as they're easily digestible then it shouldn't be that big of a deal. if you check The Master Cleanse article in curezone, you will find that people have had success with the cleanse while eating cottage cheese w flax. some nutrition could amp the body to cleanse better. i don't think you have to do the cleanses by the book, it's made that way so that it's easy and simple for people to understand and follow through. oh! i highly recommended taking sauna baths when cleansing! i wouldn't do a cleanse without it. best of luck.

Do The Master Cleanse by itself. That's the only way its worth doing.

The Ultimate Fast is a bunch of B*%*s*~t.

The b&P's need food to work properly - to keep things moving through. Without it your system just gets bound up.
You may as well just be doing a Water Fast because the Bentonite absorbs the small amount of nutrition available on the Master Cleanse.

My opinion - This thing was invented (with its gimicky name) to mess people up!!!
