I have done the MC several times & each time is different. I can't tell you what to do but I can tell you what I would do. I would stick it out. When I did the OJ fast I developed a fever for 2 days it got up to 102 so I just got in a hot shower, wrapped up in a robe w/out drying off & climbed into bed - I woke up drenched in sweat & the fever was gone. I believe it was my body doing what is natural & after that I felt much better. I have experienced severe pain in the kidney area too & I just assumed it was an old infection burried deep within & the cleanse was pulling it out. I would drink lots of water, I wouldn't do the swf anymore, but make sure you keep eliminating by some method so you are not flooded w/ toxins your body is trying to flush out. I would end the MC w/ a liver flush & follow up w/ colonics or enema. If you have never tried the LBB I would suggest trying it - it has helped us alot & I much prefer it over that tea or swf. I would also suggest a kidney cleanse, I know the MC is suppose to clean the kidneys but just for extra help in that area I would go for it. Are you posting at MC forum? Pepe is very helpful w/ MCing info & experience as well as Somer. You may want to direct your questions to them. Good luck & congrats in getting this far - awsome job!!!!
