Everybody is different. Since my TT I have found that when I am in a hyper state I get insomnia. When it flips over to hypo all I want to do is sleep. I was started out on too much synthroid initially. I would sleep for 1 1/2 hrs, wake up for a while and then go back to sleep. 1 1/2 hrs later I was up again. That went on all night for about 6 weeks until my levels started to normalize. Slept very well for about 3 weeks but, because my Dr was still playing with my meds, I went into hypo mode and couldn't stay awake past 7:00 PM. Then I'd sleep all nite. What I'm finding now, 4 months later, is that the closer I get to "normal" levels the better I'm sleeping. I think it just comes with time. What helped me was a very understanding boss who let me come in late or leave early if I was really wiped.
Sounds like your thyroid med is too high and needs adjusting. Call your endo & tell them whats going on. They'll have your labs drawn to see where your at. Everyones metabolism varies so what works for one may not work for another. Hope you feels better soon, I've been there and it's miserable....cjs
Its the lack of thyroid hormones in yr body now that yr thyroid is gone and you are probably Hypo.
I havent slept much myself the last few nights as my TSH decided to walk up to over 7.0.
Are you on thyroid replacement yet?
