It took me at least 5 months, it is very suptle (I think this right word, English my 2nd language). For 3 years I have been doing different cleanses and improved my lifestyle. So I was already in at least 80% good shape. But now I feel in general even better and people,like my cleaning lady, who is interested in alternative medicine, said you are much better than last year. Just my whole mood. For me it is more a general feeling since my body already was cleaned so much.
