New lab

Hi I have Graves and here are my lab

T3 free  2.80     1.70-4.20
T4 free  0.64      0.70-2.00
TSH      8.930    0.40-5.40
I take 5 mg of methimazole in the morning and 10 in the evening.
I also take  30 mg of propranlol spread out 3 x a day      

I have a doc appointment in about 2 weeks and I am going to ask them to lower my medication.  

How much should I be taking?
Why is my T4 low and what does it mean?

Thanks for the clarification on the T3/T4.  If the lab ranges on your FT levels are the same for each set of tests, it appears that those have been going down pretty steadily, but your TSH has been swinging back and forth.  

Again, based on your current levels, I would say that you have gone hypo and need a decrease in med.

Jan  thru may are past lab results in may my tsh was 0.022 not 2.022.
All the result for T3 and T4 are free.

I am having some aching feeling in my legs and arms.  I have a slight headache. That wont go away.  Not sure if that is allergies or from the thyroid levels though.  A little moody and little to no energy.

Are those past T3 and T4 results, free or total?  Makes a big difference.

Your current results indicate that you are hypo and need a decrease in your med.  

How do you feel?

What were your labs before you started treatment with methimazole?

How long have you been taking methimazole?

You are now hypothyroid.  You do need to see your doctor.  He will either give you thyroid homone with your methimazole (block and replace) or maybe take you off or lower (half) the methimazole depending on your situation.
