I've been taking 200mg levothyroxine since my thyroid was removed 4 years ago. I still am overly tired. I can literally sleep 12-20 hrs a day earning the nickname Koala Bear. Because of the healthcare system in the U.S., my health insurance will not be approve for 30+ days. I've called the doctor and told him the situation and ask for a Rx to get me through the waiting period so I can see him and refill the prescriptions ( also take Naproxine, Lisinapril, and Citalopram) refilled and my yearly bood test. He will give me the refills. What can I expect to happen say in the next 6 weeks after my last dose?
