Wow, an extended juice fast? You’ve reminded me of some of the side effects too, I think what I felt has something to do with the body expelling toxins. I remember having a weird ache in my gut somewhere too, I think it may have been the gallbladder or liver, it did go away after a couple of weeks. I did 3X a day for 3 months to start, now it’s just once or twice a day. I let you research that here’s a link to get started;

I had what it calls “worsening body odor,” but I take issue with the term. I have noticed, since the fast started, that I am producing a distinctive, but not altogether unpleasant scent. I think it is scented by the juice and thus has some vegetable and citrus notes. It is strong - I can take a shower and within 15 minutes be able to note the scent again. I kind of like it - I feel it’s my animal scent - my unique, individual perfume - irreproducible, mine.
Now, I understand that my neighbor might not appreciate my sticking my armpit under her nose and saying ‘smell!’, but I should hate to have to think that it is purely an odor of toxins as they are emitted.
