Tried various natural chelators and now have to get serious with DMSA. The others did not work for me. Found a good breathing CD to get me through things - Andrew Weil - Breathing The Master Key To Self Healing
www.soundstrue.com Its amazing the bad breathing habits we pick up

FIRST THING AM – 2 large glasses water
Krill Oil – 1 capsule 15minutes before meal with some fiber or yogurt / 1 cap bedtime
Have breakfast
After meals – dandelion combo for liver – 3X day – 10 drops first 2 weeks, then 20 drops – see how feel (www.stfrancisherbfarm.com)
reservatrol - anti oxidant
Shake - Goatein and barley grass and flax fiber
500MGS B12 sublingual for a while then 1000mg
sea salt on food for minerals
After 6-8 weeks – take 6 amalgams out

Then start DMSA - 10 mgs every 4 hours - 2 days on 4 days off and see how I feel - adjust as necessary. Get to 25mgs every 4 hrs 3 days on and 3 days off. I believe that cilantro is ONLY okay to take with DMSA, the binding agent, otherwise avoid it.
After 3-4 months might add some R+-lipoic low dose every 4 hours - http://www.r-lipoic.com/
