RAI (Radioactive Iodine) for Graves Disease - do your thyroid antibodies go down?

I had RAI for graves disease to nuke my thyroid on Tuesday, 25 July 2017. This page shows a graph of my antibodies reducing over the following years. I see this question asked in many places across forums and wanted to document my experience with data.

For me, the answer was yes.
But it took about two years. You an see thyroglobin antibodies actually entering normal range. Thyroid peroxidase antibodies also continue to decline, though they remain slightly above normal. Perhaps a higher dosage of RAI would also have returned this to normal range.
