first of all.....EXERCISE and time are the fastest way to naturally clean your body of thc. As far as the fiber....I THINK you are right. I would suggest reading and practicing the dilution sticky to the letter. ALSO...I don't think the sticky mentions about adding a creatine supplement to your diet or eating red meat for 2 days prior to increase the creatine levels in your body. If they test the PH level you might want to eat a few rolaids with the dilution method AFTER you start voiding clear. Passing drug test with the dilution method is very possible but you almost need to get it down to a science. If you have time, order some test strips off EBAY (which will cost about $1.25 each with shipping. Practice the dilution method with test strips at home before the real deal. Don't be surprise if you go through many test strips until you see how long THC will stay in your body. EVERYONE'S body is different therefore all answers will vary.
