Yeah call your doc. The eyelids thing is quite noticeable, it feels HARD to keep your eyes open and you look sleepy the whole time...? The weight thing - i actually lost my appetite with it (everything seemed to take ages to digest and i hated feeling full and uncomfy - ooh! Constipation - another symptom!!!) BUT because i was exhausted, when i DID snack it tended to be on high-sugar things, to "give me a lift" so that will have been adding calories...

Re: the fitness thing, that's more of a personal one, not noted, but my GP did say he wasn't sure how i was managing to keep training for my half marathon when i was ill - it took me WAY longer to increase my distances than it should have and instead of adjkusting and getting fitter my body just kept getting injuries. I'm still the sort of person who needs 3 weeks at the gym to "come back" after a week off, even medicated, so maybe some of it's genetic?

It's not at all uncommon after we have a bub for cracks in the thyroid system to show. Best of luck getting it sorted - mneantime SLEEP more - when i was exhausted with my thyroid i was sleeping 11 hours a night and STILL couldn't get off the sofa most days, unless it was to run.
