good luck to you. my tsh went up into the low 90s in september -- but that was because of my getting food poisoning 3 times in a row within a week. the things i got sick on were high in bromide. 3 weeks later, after it all worked its way out of my system, it dropped back down to around 8.
i am now on a gluten free diet.
blessings to you and yours.
It will take some time to find the right balance but eventually you will have normal levels on appropriate replacement medication.
