After doing the complete b12 protocol for a while, I've been getting urine and stools that smell a bit swampy / funny, and I've heard that may be a sign of heavy metals. I've been sooo tempted to just flat out buy an infrared sauna and try it out, but I want to get more educated before spending $350 Canadian on amazon.
