My doctor reduced my dose of levothyroxine to 125 mcg down from 150 mcg and i haven't felt this run down since before i was first diagnosed. i have gained a lot of weight, my skin is dry and i feel drained. My doctor won't listen when i tell him how I feel and insists i am taking too much. Can i increase it myself to the dose i was on previously and see if things improve? I feel like i am hitting my head on a brick wall when i talk to my doctor.
