Oil Pulling: Unlock Natural Oral Health & Detox Benefits

I have terrible dryness as if the cells of my body are not assimilating water, and have suffered from terrible congestion, resulting in lack of sleep; literally pacing the floor all night when my sinuses are really bad. I found this site and immediately started pulling with organic cold-pressed sesame oil. I did this faithfully for a week, with no difference. What am I doing wrong? I read the testimonials and had such hope. Perhaps for a chronic condition it takes much longer? Please advise, I am desperately trying to cure this.
