i split it into two sessions, spaced a year apart.
I always chelate, even as I type this, even though I haven't eaten any pills and I don't have any IV's dripping in me. The body is constantly detoxing itself. All one needs do is give it proper conditions to enable it to do its job to the max. Kind of like having a mechanic, and making sure his toolbox is full, versus the case where you give him a rock and a pair of pliers and expect to change out the rod bearings in your model T.
