i think you will see more improvements. your are 14 months post removal. Even andy says many people will feel worse for 12 months.

I did not chelate and my mercury hair levels dropped to nearly zero. (they were not very high when i had amalgams)

I had some improvements but still lots of mental symptoms.
I believe chelation is important for brain detox.
I am 13 months post removal and did 4 rounds of ALA recently. I did notice improvements. Wondering if you had intellectual improvement with ALA?
