I too have ocd but i just thought it was normal, it doesn,t stress me out and i would never have thought it was to do with metals, as i know loads of people with it who dont have fillings, mine is mild like, when im brushing my teeth, i have to brush them at least 60 times on one spot or somethings going to happen, and i always find that there are always 13 stairs in houses, so i miss the last one because 13 is an unlucky number. David Beckham has it! Some peoples lives are ruined by it i have seen programms on tv. Dawn
