I had a total thyroidectomy last october(9months) and have been taking thyroxine ever since. My doctor keeps changing my dose after each blood test, every 6 weeks, in response to it being hi/lo. Each time they only test my tsh. They told me this is the only test needed as i have no thyroid. Is this correct? My latest tsh is 0.53, previous one, 6 weeks ago was 0.4. My current dose is 125mg. Trouble is I'm feeling pretty awful. So exhausted despite having lots of sleep, no energy, appalling memory and concentration. I cant keep going on feeling so tired. Its not easy when i have a 18m to entertain!! Ive been reading about desiccated thyroid. Anyone know anything about this? Also when should i be taking my thyroxine as read 2 hours before breakfast and no other meds at same time? I take meds for acid reflux at same time about 1 hour before i eat. doc told me today to come back in a year!! I think she crazy and have made an appointment to see her next week!! any advice or thoughts are greatly appreciated as i find this whole thing very confusing and frustrating. Thanks!!
