That seems like a good sign if your adrenals are starting to produce more cortisol on there own. I agree that you should take a break from chelation when reducing the meds so you can easily pinpoint any changes in symptoms.

My chelation is going extremely well...I did a 6 day round at 17mg each ALA/DMSA and it was really smooth. I just really hope this chemical sensitivity of mine eases up soon, it can be quite a hassle at times.
