That's fine, that the fillings are already out! Now you should detoxify. As you obiously lack money here a hint: Sport is one of the best detoxifyer.
Oatmeal partly binds mercury in the guts. Enemas are a cheap help. And a castor flush is not expensive: Get up early in the morning, mix two tablespoons full of castor oil with ice-cold orange juice (best with the mixer) drink it, go back to bed, sleep, and get up to run several times to the toilet...
In the Amalgam Forum you probably will get many advices on detoxifying!
