Yes, had Graves disease, I was 'tired but wired', night sweats, anxiety, bad guts and weight loss, and double vision on waking... It is sortable, but do get checked asap - when my GP got my blood tests back, she called and told me to come in straight away.
If it is, you'll probably be started on carbimazole while waiting for an endocrinology referral. Your GP may not test for antibodies, it might be up to the endo, but it should be done. You may also want to get an optician's appointment while you're waiting and get your eye pressures checked. If you smoke, stop! Selenium supplements, or brazil nuts, can help.
Elaine Moore has lots of info online about it, but don't go mad googling - it may not be Graves at all! But if it is, once you get treatment, you'll feel better, it just takes a little time. Good luck!
(And it's a good dentist you've got there!) 😄
