Re: Is this Sibo or Candida?

See how you go mate, but from what you have just said, sounds to me like the Nyastin was having a good affect. Just remember the first 3-6 months are treacherous for odours. When what ever is inside Candida and/or bacteria starts dying off the odours will be at their absolute worst. Toxins will be dumped into the bloodstream and will overburden liver, lymphatics, kidneys etc. Mine got much much worse before it started improving. I think it's going to be inevitable that you will need to get all the rubbish out of you. You could try taking bulk probiotcs, digestive enzymes and a good fibre supplement to push everything out but It's not usually that easy to fix. From all my experiences I have found the body to be chocked (and I mean chocked) with loads of old feces and fermenting foods. Support the liver and kindeys and I recommend reading some of Max Gerson's book.
Good luck.
