You should wait until you wean your child before having your amalgams out.

I also had cystic acne mostly on the lower part of my face and along the lymph glands in my neck. I was taking calcium at the time (which I later found out to be bad for mercury toxic people because of low magnesium levels) and also on a high sodium diet (by dr.) to try and retain fluids because I was so dehydrated. I finally learned that the acne was my body tring to get rid of the excess calcium and sodium that it didn't want and was already over loaded in trying to detox because of the mercury.

Pay close attention to what you eat and drink lots of water to help flush out the unwanted toxins. Your skin takes over if your kidneys, liver and colon become over loaded.
