Perhaps you might want to start off more slowly w/some liver flushes to clear out your liver. Go with your intuition and go from there. I def. think you should give the Humaworm a try, but perhaps you might want to find out more in re: liver flushes and also a bit of colon cleansing, too. Some people want to dive in head first, but in your case, given your history, maybe it makes more sense to give your body a good down deep cleansing first via liver flushes and colon cleanses and then go from there. If you can afford it, I recommend trying seeing a person who is trained to do colonics, or else consider the Humacleanse, IMO. Again, go with what your instincts tell you
