Hi I have posted a couple of questions about methimazole in the past, i have weaned down from 10mg to 2.5mg and last sunday i stopped taking it. I feel different i have a lot of pressure in my head and feel off balance. how long does the medication take to leave my body after i stopped taking it last Sunday. Is there any changes my body will go threw. I dont know if i am having anxiety from not taking the medication or is it my body adjusting to not taking the methimazole? I have had normal labs for over 2 years on the methimazole. Thanks for your time and happy holidays.
