Hi I am diddums and starting my thyroid journey. The GP has been 'keeping an eye' on my reading for over 4 years . I have recently been diagnosed and put on 50mg of Levothrioxine, but am finding symptoms not great. I get so tired and 'brain fog' is a real issue. I describe it as feeling like premature aging. I have discovered the T3 debate and wonder how proper healing can occur. BTW I have to wait 6 months for another blood test to have readings checked again!!!!
