It will take some time to find the right balance but eventually you will have normal levels on appropriate replacement medication.
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.
