I take 3/4 of a 90 twice daily= 135 total
I take three grains of Armour daily, which totals 180 mg. So, 60 mg isn't really all that high. The main thing is to adjust dosage as necessary to raise your Free T3 level and Free T4 level high enough to relieve any hypo symptoms.
If you will give us a bit of history about your symptoms, diagnosed cause for being hypothyroid, and post your thyroid related test results, members will be glad to respond further.
