I did a cleanse for 5 days: we fasted for 5 days and in the morning drank 2ltrs of salt water to induce a movement. Then we had a dose of a table spoon of Bentonite and psyllium husk at 9am and another at 1pm. We drank at least 5 ltrs of water a day.
It was miserable. I got extremely weak and depressed and my brain fog was overwhelming - I felt like I was underwater and I couldn't even put together a simple sentence. There was no way any emotional feelings could have been addressed since I couldn't feel or think about anything at all. There was no openness, no revelation, no release, no relief, nothing but sheer misery at a pre-verbal level. SOmeone on the cleanse told me that everyone was TRYING to stop thinking and 'how wonderful for you to have succeeded!'. Clearly, those people did not know what brain fog is or they wouldn't envy it.
Coming out of it, I am weaker. My brain fog is much worse and my bowel movements are still no more regular or full.
I'm already on a sugar-free-wheat -free-yeast-free diet and I always drink at least 4ltrs of water daily.
There isn't any 'mystical side' to colon cleansing as far as I can see. Or any real, life-changing health benefits either.
