Thanks for all the replies!

I did have regular bloodwork done a few months ago, do they check your thyroid levels with that? I know my bloodwork came back normal, and they were particularly screening for pre-diabetes (runs in the family) but I don't know if they checked my thyroid levels, I just remember that everything came back normal... I just googled signs and symptoms, and the only ones that match me are the BP related ones, fatigue (I'm out of shape) and intolerence to heat (being in a hot stuffy car makes me lose it, pretty quickly) nothing else seems to match, so I doubt it...
Any thoughts?<< love that sheep!
