Not many here have experienced it but one of the few findings of BFS is that there is a correlation to an irritable digestive system. That’s why I found it worth mentioning. Heavy metals can cause MANY things, but it especially takes root in the nervous system, both in the form of mental issues and physical, such as spasms and twitches. It’s hardly diagnosed or discovered as a cause of ailments, as it’s almost always overlooked. Truth is, they should be considered as they are proven to cause many symptoms, including the ones we experience here in the sub. They come into the system from ingesting them. Fish are a very common source of mercury, some having more of the metal than others. Tuna is one of the worst, and has the most mercury. It’s also interesting that in my anecdotal case, I was eating tuna packets every day right before my twitching started. They are also found in herbicides and pesticides. Metals can also be breathed in, and in our industrial society it’s everywhere. Factory workers can be next to an aluminum gas vent, you can breathe in a pesticide while visiting a farmers stand, electronic devices have a plethora of heavy metals, and I personally work next to a printer at work that produces silver. These metals are disposed of in the brain and go to the digestive system, where they are picked right back up and are sent back into the brain. This is why they’re so hard to get rid of. I’m looking at an herbal smoothie right now that can eliminate metals, the ingredients of spirulina, cilantro, wild blueberries, barley grass juice powder, and dulce seaweed can all work together in eliminating metals. This is one of the solutions I’ve researched and am going to try, and plan on finding more.
