amiodarone/hyperthyroid symptoms

I was given IV amiodarone and oral  in late May of this year. Also had a CT scan and cardiac cath in June. (more iodine).Since October symptoms of hyperthyroid and TSH last was 22. and free T4 was 1.35. TSH was higher before this test a month ago but dropped again. Question is how long does this last from this drug?? I am just feeling warm and can't gain weight. Taking tapazole 10mg daily and weigh only 90 pounds. Don't do well with most meds. Amiodarone gave terrible side effects  and had to stop after only a week of treatment. Had cardiac ablation end of June and doing well from that. I hear side effects from this drug last months (how many). Would like to get back to normal again. Not taking any amiodarone or similar drugs now. Appreciate your input. Guess this is a powerful drug and don't want to take it ever again. Doppler was negative also.
