Hi Adam:
A few months ago, I started wondering about the very same thing, but I couldn't find the information I was looking for, so I did a little experiment myself. I went on a 21 day
Water Fast on July 22 and a 21 day
Master-Cleanse on September 22. Keep in mind that it's possible, though I don't think too likely, that I was already much healthier when I started the
Master-Cleanse than when I started the water fast.
During my water fast, I did a
SWF (Salt-Water-Flush) maybe twice (altogether, not per day!) and laxative tea once.
My "regular diet" is almost 100% raw; Approximately a couple of times a month I will eat toxic food, but usually not the really bad stuff (hydrogenated oils etc). Sometimes I just don't eat for a day or two.
So anyway, in terms of "difficulty," meaning how tired and weak I felt, if normal (healthy) food is 100 and a
Water Fast is 0, then the
Master-Cleanse is somewhere around 95.
I'm very thin. After the
Water Fast I gained a lot of weight, which also felt quite good. Succulent, so to speak. After the MC, so far, I have not gained quite as much, and I also didn't lose as much weight on the MC as on the water fast.
The subjective evidence of "cleansing," during the fast (such as tongue coating, heart rate) and after (skin, eyes, mood) seems to suggest that the cleansing starts much faster on the MC, but after day 2 isn't significantly different from a water fast.
There is also an additional complication in my case, which probably doesn't apply to most people: One of the major benefits of the water fast was that I was so weak, I had practically no sex drive, which provided welcome relief from my addiction to orgasms. I believe it is this which made my eyes turn green (from hazel) during the water fast. On the MC, I pretty much continued with daily sexual activity. My eyes became clearer, but it was more like darker shades of brown and blue rather than green. Hehehe, this is starting to sound too weird.
Spiritually, if you want to call it that, the MC didn't feel like a fast at all.
For my next fast, if I ever do one (I'm probably going to get a job for the first time in years), I would like to do the first 3 days on the MC protocol and then do nothing but water and a daily SWF.
Here's another observation that just came to mind: After the water fast, I started disliking alcohol much more than before. After the MC, I started disliking cheese, cooked rice, chicken carcass, really pretty much anything that's not a raw fruit or seed. These effects, interestingly enough, occured about a week after breaking the fast each time.
Speaking of breaking the fast: both times, I ate fresh fruit to break the fast, and both times, I started binging on "anything in sight" the next day. After the water fast, that presented no problem whatsoever, but after the MC, I literally passed out from a couple of pieces of pizza. This has happened to me before when eating something highly refined/toxic after a long period of mainly or only raw foods. Apparently it makes me look really pale and sweaty and my eyes roll around in a weird way, hehe, I wouldn't know. I just feel it coming on for a couple of minutes, then I stop to see or hear anything, then I'm completely out for a few seconds, and when I come to, someone is usually holding my head and asking me if I'm alright. Thank God I never feel nauseated during these episodes. As a matter of fact, it's almost pleasant. It's probably the closest thing to a heroin high I have ever experienced. Sad when I think of it that way, hehe.
The way to interpret this might be that the MC is in fact more cleansing than a water fast. Another indication of this might be the speed at which food now moves through me. I have never had any problems in that regard, but it seems like what used to take maybe 12 hours from top to bottom, now takes 8.
My lungs seemed more cleansed after the MC, but that's probably just the cumulative effect. I used to breathe highly toxic air until a year ago, now it's slightly better, so I'm not surprised that my lungs are recuperating.
I don't go to a psychiatrist, but I guess I have had symptoms of "depression" for a long time. They are worse now than ever in the past couple of years. I figure that means I'm more cleansed, more "natural" now than before, so I more strongly dislike the hell we live in. Maybe I should talk to a shrink. I wonder if I am actually depressed. It's not like I'm going to kill myself, but death is definitely the only thing I look forward to. I "find it difficult to see meaning or purpose in my daily life." Hello! There is no meaning or purpose in daily life. If someone else doesn't understand that truth yet, too bad. I am hesitant to do anything. Whatever we do somehow feeds into the machinery of destruction we have created for this planet. But more importantly, nothing we do matters anyway. A few billion years from now, it will all have been erased. The immortal part of us will remain the same, no matter what we do. I realize this last statement is debatable, but the way I wrote it represents my personal faith or belief, not a psychiatric disorder. The rest follows logically from this assumption (that death is exactly the same as change, it other words, immortal means unchanging).
So there!
