I know, I'm always curious, too. My last two fillings have been gone for 2 years. I've stayed steady with about 400 mg Iodoral/SSKI. Currently on 200 mcg selenium, but have taken as much as 1500 mcg until my stock was full. Several years ago I knew I'd topped out at 800 mcg when I started smelling really garlicky. Then I didn't take it for awhile. This time, what with all the detox and balancing with iodine, I never smelled garlic, but my sleep got more restless than usual, and reducing the selenium fixed that. Thinking about it attaching to mercury to usher it out makes me want to be sure selenium is topped off. As for the ALA, I've been taking 300 mg time-released for 14 months. Since I wasn't sure this would have an effect for mercury reduction, I took it at least to support my liver. Hubby had good results with it, and I hoped it would help me as well. Time for a blood test soon.
