I was on the levoxyl, then Synthroid for three years. I pray I never go down that road again.
What many, many doctors will not tell you is that those two meds don't work for an awful lot of people, because their body doesn't convert the T3 to T4. So even though your TSH says one thing, that is not necessarily the amount of thyroid hormone circulating through your blood, nor does the same number work for every person.
The very hour I took my first dose of Armour thyroid, the pain eased, the brain fog left, and I was me again. Yest it has taken me 8 years to find a local doctor to willingly prescribe it to me.

It is your friend.
BTW, I remember sitting in the local endocrinologists's office, waiting, waiting, waiting, then 2 reps for Synthroid came in with boxes and goodies. After they left, the endo told me I should be taking Synthroid, not Armour. I said "But I feel good." She didn't care. She told me to stop taking it and return in 3 weeks. I said "But the pain, it'll come back." She didn't care. Why? Why would an endo prefer you go through misery, so they can put you on a drug you told them never worked for you?
