QHad thyroid removed 9 months ago. Started 137 mcg levothyroxine. Had no energy, dizzy & brain fog. Free T3 & free T4 in range but Tsh dropped to .014. Switched to synthroid & brain fog went away. Still no energy & dizzy. Dropped synthroid to 125 mcg & Tsh increased to .062. Dropped synthroid to 100 mcg & Tsh went into range at 1.8. Still no energy, occasionally dizzy & now beginning to have anxiety symptoms. Edno Dr. suggests going back to internist. I'm getting really tired of being tired all the time. Any ideas?
