How can someone have trouble sleeping when they're Hypothyroid after having Hurthle Cell Thyroid Cancer?

[nighhhh]

I'm a seventeen year old boy and when I was fifteen I was diagnosed with hurthle cell thyroid cancer. I had my thyroid removed, and went on the low iodine diet for the radioactive iodine treatment. Luckily, I have no more problems with the cancer - and haven't since. However, since my treatment my grades dropped significantly, and I developed really bad sleeping problems. I recently was prescribed Aderrall because I found out it's pretty common to develop ADD after having thyroid cancer because your hormones can become so unbalanced. But, my sleeping problem still persists. I never can fall asleep at night, and I struggle alot to wake up for school but once I am up - I'm wide awake, this will go on for a few an extended period of time (a week or two) then I'll crash for a day and the cycle continutes. Some would assume that my thyroid hormone dosage is too strong, but in fact I would be considered to have hypothyroidism since my doctors want me to keep low thyroid hormone levels so I don't "activate" any thyroid cells left in my body. I was wondering if this was common among people who've had thyorid conditions - cancer especially - and out of Melatonin, 5-HTC, and Laverian Root (I've done a good amount of research and they all apparently help with sleep issues), which one would help my sleep problem more significantly (helping me fall asleep, and get asleep but without making me feel groggy in the morning and causing me to fight to get up)? I really want to live a "normal" like again and my life hasn't been the same since my surgery over two years ago.

I take levothyroxine, 200 mcg - I don't exactly know what my levels are personally; however, they were checked no more then 4 weeks ago and my endocrinologist was happy with the results.

Yes, it is important to keep levels low as often the trigger for some of the cancers is the thyroxine itself (medication as well as what is normally in the body prior to removal of thyroid)  However I wonder if your dose is not adequate for you.
Do you have any latest blood tests and the reference ranges? What thyroid medication do you take? What dose do you take?

It sounds like it could be too high. Insomnia like you have is often related to hyper not hypo (though it does happen)
I hate to be a party pooper but normal is not likely to be normal ever again. You are going to have to learn to be the best you can and be aware of symptoms and deal with them as you go.

  Post your levels here, and if you haven't got any, I suggest you go get some done, TSH, Free T3 and Free T4 are what is needed.
