Have you experienced fatigue, nausea, headaches, dizziness, skin, eye, or nose irritation, or had poor concentration to just be told from a health care professional that it is "nothing" or "untreatable"?  From the air we breathe, the water we drink, to the materials we use, our living and workspaces are heavily affecting how well we feel.  If you can say "yes" to any of the above, there is a good chance you were or are experiencing sick building syndrome or SBS.
