Does taking thyroid hormone replacement at night cause insomnia?

so I am a 16 year old girl been on levoxyl for about 6 months for hypothyroidism due to radioactive iodine previously hyperthyroid. Anyways, every since I started taking the medicine I have a terrible time falling asleep due to racing thoughts and terrible anxiety. I had my levels checked a few weeks ago that indicated that I was slightly hypo TSH 5.7. I know its not due to hyperthyroidism, so is it better if you take it in the morning?
