AsianGuy,
I'm not a real believer in long term detox issues. I do believe that there is a transition period where your body, intestinal flora, etc must adapt to the new foods and the old bacteria in the intestines will die off creating some toxins but this should be short lived. Within a few weeks your body should adapt to your new diet, however, expect things like percent body fat and other body composition factors to change much more slowly - say up to a year to 18 months before everything like body mass and weight stablize.
I also found that raw vegetable juice caused major problems for me. It sounded good in theory but caused bloating and loose and very smelly stools when I consumed it. Once I stopped drinking it altogether, stools firmed up, bloating went away, and the horrible smell was gone. There are also a large amount of alkyloids in green juices and I often experienced cloudy urine when drinking any significant amount of the stuff.
I spent almost 20 years as a diehard vegan drinking large amounts of green juices because the gurus said it was the right thing to do. My body kept telling a different story but I refused to listen - even though my health was clearly deteriorating. The gurus all told me it was detox and of course I believed them. So I suffered through "DETOX" for about 20 years. I even did a 31 day water-only-fast that almost killed me, but the gurus told me that I was so toxic that this was the only way I could solve the problem. It took me over 2 years to recover from this fast and the detox symptoms continued.
Funny thing is that when I stopped drinking the green juices, cut out the carbs, and ate meat and fat instead, all the detox symptoms cleared up within a matter of weeks and have never returned. My mood stabilized from the roller coaster ups and downs, my type 2 diabetes went away, my blood pressure dropped from 150/95 to 106/60, cholesterol went from 235 to 189, triglycerides went from 500 to 62, and horrible migraine headaches that I've suffered since I was a teenager completely went away.
My suggestion? Ditch the green juice. If you want some carbs then eat a bit of fruit once a day as a small snack, otherwise eat meat and fat and eat it as raw as you can tollerate. Your body will adapt fairly quickly and I think you'll feel much better for the change.
Hope this helps,
Lex
