After a very rough weekend I got to see the doctor and get my blood results:
TSH 0.01 (0.35-5.0)
FT4 27.1 (9.0 - 20.0)
They didn't bother with T3 by the look of it but did something called a Packed Cell Volume which is 0.36 (0.37 - 0.47) and I have no idea what that is.
He has also given me Zopicolone that should help me sleep but I'm a bit wary of taking them after Googling!! Oh how I hate Google....
If anyone has taken them before I'd love some advice.
