Hey I have similar experiences, have graves for years but now my symptoms range from hypo, fatigue, chills etc to hyper sudden sweats and easily hot tempered.
Personally I found the hypo symptoms worst off as it can ruin the day when you feel your energy is completely zapped.
I have found great comfort in taking an iodine free multi daily and getting a lot of rest, going gluten free whenever possible and try not to be stressed.
Good luck!
