Go to the doctor. Sometimes this could be neurological
Hmm do you get heart burn? Could be the acid reflux causing the taste, could also be an abscess tooth causing it, fish poisoning (maybe you ate some bad fish), excessive use of selenium can case various adverse symptoms, post nasal drip (taking any medications that you inhale?), could be either mercury or lead poisoning, see if you can rule out any of these.
Let me know!

I would assume that perhaps you have a cracked filling that is leaking in you mouth. The bad side is that they say when someone is about to die they have a metallic taste in their mouth. First go to the Dentist as I am sure it is more this than the other!
