Diagnosed underactive 7 years ago, on 50mcg to start with but increased to 75mcg 5 years ago. Recent bt showed tsh 1.85 which gp says is normal. Feel tired and lethargic lately and slightly achey.
Just don't have the energy at the mo, was wondering whether to take an extra 50mcg once a week, or should I return to the gp to be told I'm within normal range.
