Neogastonist is not working for me

I had a friend years ago who pretty much lived on drugs and junk food. Seriously, the guy never ate fruit or veggies. He wound up living with a vegan couple and started eating healthy(but kept doing drugs). The first 2 weeks his body just couldn't handle it and he sh*t like all over the place, and I guess it was this really weird detox sh*t. He looked lethargic and haggard. It was one of the weirdest things I've seen.
