I'm not taking any prescribed Thyroid Meds, but I started taking a natural Whole Dessicated Thyroid Concentrate about 3 weeks ago because I was feeling exhausted.

I'm also taking Isocort (not a prescription either) for my Adrenals, and Colostrum among other supplements. The Colostrum really helped my energy level.
