actually if you chelate, the chelator will mop up mercury mostly in your bloodstream, maybe loosen some in other places... your body eliminates it... you feel good at first for a day, then a few days, then whump down you go because your blood stream is filled uo again... so you chelate some more... you feel good for a few days... then whump... as time goes by those feeling good periods get longer and longer as your body's load of heavy metals and other junk is lessened. but it takes time, anywhere from a few to several months to really be able to hold onto a couple weeks of feeling real good in between bouts of chelating/detoxing.

just stay at it. You are probably just getting different effects from different things interacting in your blood as your body eliminates them. But if you have set yourself up to eliminate, eliminate you will. drink plenty of water.

spirulina makes me feel great too. you must be absorbing it well. It's loaded with vitamin a.
