I live in SF, CA. I've posted before about issues I have after removing part of a wall in an old house 6 years ago. Something came out. Mold, chemicals, lead dust, heavy metals, not sure.

So now, it's as if the substance/s has been following me around for all this time. I can't prove it, but it feels like it is, clinging to items I've owned. It's like spores or something are around, blow around, ending up on or close to where I sleep and work, and I thinking I'm breathing them in all night, and having a reaction, as almost every day I wake up with head pain, sinus pain and dizziness.

In my head, it's like a pulsing, like there's something there. And I get irritable, and it affects my thinking. I keep thinking there's some kind of a head detox thing that I don't know about, and should do.

Also, a chunk of one of my molars broke off years ago, and the next one cracked recently. Side note, my libido is kind of low, and I read lead, even at a low amount, could be the cause.

Health devices: I run a Germ Guardian Air Purifier, and an ozone machine. I think they help, but I have to leave the room while the ozone machine runs.

I am in my mid 40s, about 155 pounds, always thin. Someone wrote to me about megadosing Vitamin C, like 5-20 g/day (5,000 - 20,000 mg/day). I feel it's time, since I've tried so many other things.

I had more info from bio-electric tests when I lived in LA and FL. As I recall, it was lead, tin, maybe mold, and other heavy metals. I forget all the details. Still looking for someone locally to run tests.

I'm hoping vitamin C will help. I've researched for the best brand, and found many different brands and options. I know to be wary of GMO, and of any made in China, and some other restraints. It seems powder form is the way to go.

Also, I am reading Rami Nagel's "Cure Tooth Decay". Per the book, I eat a kind of indigenous diet, Weston A Price based (kind of like paleo). Mostly veggies, sweet potatoes instead of grains, meats, liver, raw milk, eggs, salad greens.

Now, I like natural products, not too 'altered', so, these are brands I am considering:

http://www.holisticdentalstore.com/herbal-vitamin-c.htm (per Rami Nagel's book. He does not mention taking to bowel tolerance)
https://healthforce.com/longevity-immunity/truly-natural-vitamin-c
http://www.bolthealthsupplements.com/ProductDetails.asp?ProductCode=143043326...
http://www.iherb.com/Starwest-Botanicals-Rosehips-Powder-Organic-1-lb-453-6-g... (looks good, but I don't know if it works with the 'bowel tolerance' loading)
http://www.radiantlifecatalog.com/product/pure-radiance-c/119

Any recommendations on the above brands, perhaps another, or anything else that would help?
