If I were you I would stop the Antibiotics and seriously consider the mercury toxicity issue. The fact that your mom had 20+ fillings is EXTREMELY telling. I highly recommend checking out Andy Cutler and his two books. Both are must-reads if you are mercury toxic, which you almost certainly are being exposed to mercury from 20 fillings in utero. IMO Cutler is the leading expert on mercury and mercury chelation and you should at the very least familiarize yourself with the knowledge he has to offer. He has two books: Amalgam Illness and Hair Test Interpretation.
I was gonna link you to a torrent of Amalgam Illness, but I guess I can't post any links since I'm a new member here. If you google "Amalgam Illness torrent" you'll find a torrent on the first link that comes up.
I plead you to look into this issue and read through Amalgam Illness. It is likely the major catalyst behind your health problems.
