Hi there, I've had the same thing. I used to sweat and smell like metal. So yeah, metals/mercury are coming out of you.

A good thing to do if you can handle it and if you can't afford a sauna, is to have hot baths using epsom salts or (baking soda and sea salt). That can induce further toxic release through your pores and to shower off after it or rinse yourself off with fresh water afterwards.

Also, if you can handle it? Exercising also. particularly doing it inside and possibly even overdressing a little at the time. This is if you do sweat. Some people with this hardly sweat, some sweat too much.

If you have a treadmill? that's a good one to use. Particuarly the ones that you can put on different levels like walking up hill.

A lot of vitamin C powder in water is good to help also. Any antioxidants will help - vitamin E, vitamin C, selenium (selenomethione form is best) etc.
