I can see that ignorance is bliss! Several years ago, I made a batch of Rejuvelac -- since I was unsure as to the result, I was a little nervous about drinking it. Anyway, I was pleasantly surprised at how delicious it was. No remarkable side effects.
Perhaps I had done all of that work after I had done my kidney cleansing and liver flushes (3 of them, 2 weeks apart -- I must have got out about 800 stones of various sizes -- amazing!). Perhaps that saved me!
Now, it's time to get back on the health bandwagon.
