Sorry to hear about your troubles. I've been there recently, too, so I understand.

Sophie's thyroid issues didn't appear overnight, so it may take a while. The thyroid levels take less than a month to return to normal, but the physical symptoms may take a little longer. It took Emily a while to stop eating so much, but she had been starving for a good while. Some of this was psychological.

Just watch her symptoms to make sure the meds aren't too much.

And good luck.
