I've heard people recover from symtoms in a matter of weeks without detox, it depends on the seriousness of the symptoms, I suppose. Go to these websites.
At this one, click on number 26, but also be aware that Almagam dental fillings can also be causing problems because of the mercury. Another consideration with Oil Pulling would be the possibility of the fillings being loosened or releasing toxic mercury. Magnetic Clay Baths are good for detox, but any detox might overload one part of your body with toxins as they exit (I don't know, but caution is wise).
