I was exposed to mold too, and I had the head pulsing and a lot of those other symptoms. Brown seaweed will help with the mold exposure. Diatomaceous earth would probably also help as well. If you're certain about the mold exposure, then you need to get rid of anything that has been exposed to it. The spores will still cling to those items and spread. Apparently even just washing exposed clothes doesn't help much in many cases. Have you looked under any furniture for potential hiding places of the mold?
Also, try looking into candida, as that can also be implicated in cases like this. I can't post the link, but the site body ecology has a good checklist.
