Interesting.
I went to a vegan health spa for a week, and they offered me a “colonic cleansing” to augment my program. Not sure what that involved - probably a enema - but whatever, I didn’t like the sound of it, so I passed.
Instead, I just stayed with the vegan food, so there was no meat, no dairy, no alcohol, no coffee, no soda, and so forth. I was never much of a drinker, but the coffee withdrawal - oh man. But I stuck it out, and by the end of the week I felt great.
I remember walking through the airport on the return, and it felt like I had been implanted into someone else’s body.
