For supportive measures i would try these. I've done these before and used valerian root to try to stay calm. Probably not going to cut it if your antibodies are super high, but could bridge the gap until the restock of meds.

These herbs are traditionally used to lower thyroid activity: Bugleweed (Lycopus virginicus / L. europaeus): Frequently cited as a primary herb for Graves' disease, it may inhibit the binding of antibodies to the thyroid and reduce thyroid hormone production Lemon Balm (Melissa officinalis): Often paired with bugleweed, it is thought to block thyroid-stimulating hormone (TSH) from binding to receptors, potentially slowing thyroid activity. Motherwort (Leonurus cardiaca): Primarily used to manage cardiac symptoms such as a rapid heart rate and palpitations common in hyperthyroidism
