This is Dr. David
sounds like you have battled thyroid issues for a long time.
what has your TSH levels been most recently?
are your doctors tapering you off of the methadone at this point?
I see you are in the psychiatric ward at this moment?
do you have a history of mental illness or psychological issues?
you have to make sure your TSH level is between 0.3 and 3.0
TSH levels above 3.0 means your thyroxine dose is not enough.
your motivation can be low possibly from too much methadone or depression or low iron or possibly from other causes as well.
euthyroid means your thyroid hormone levels are correct and normal
methadone would not affect your thyroid hormone levels.
you didn't answer if you have a history of mental illness or depression
no, most likely the methadone is not interacting with the thyroxine and would not affect your thyroid system.
you still need to find out what your TSH level is.
if your TSH level still keeps going up and down, you could have a hashimotos thyroiditis
by your body making antibodies to attack your own thryoid gland causing it to be inflamed from time to time.
this can cause your TSH level to go up and down
there are treatments for this thyroiditis.
but you need blood work first to test for anti thyroid peroxidase antibodies and anti thyroid globulin antibodies.
your chemical imbalance might be causing your symptoms instead of the thyroid issue.
you are welcome
good luck with the blood work.
ask what your TSH level is
let me know if you have other questions.
if done, please leave +++ positive feedback below the chat box.
you can always reach me as Dr. David if you have other questions.

you are not allergic to the thyroxine
your body's own thryoid gland makes thyroxine thyroid hormone
why did you rate poor service?
can you show me your literature that you have about methadone stopping thyroxine producing T3?
