Know what you mean about feeling tired all day then not sleepy when going to bed - it's cruel. With me it's like I can't get my mind to settle into switching off. I'm actually sleepiest between 8 and 9 am just when I should be up and about! Interestingly the best night I had was after I had the all clear from my bone scan last Tuesday, I slept straight through to 7:30am (sadly not been repeated since) so I think anxiety is still lurking about and some depression now too since I'm getting fed up with it.

Good luck with the endocrinologist let us know know what the outcome is.
