Too much levothyroxine

Guys I think im on too much levothyroxine currently taking 100mcg i didnt take it today I plan on going to the night clinic for a dosage lowering and labs

But Ive been feeling pulsating/ and palpitations on my neck and the middle of my chest My chest feels kind of tight I feel tickles on my lower neck I also have the coughing sensation my hands feel shaky I barely feel them when im moving around but once I sit or lay down I feel them horribly

At the hospital I was told I had nothing and was sent home

What can I do to stop the palpitations??

What have yall done?

Im drinking iron with copper since i was low in iron

Vitamin D

Magnesium and Pottasium in small amounts

1 brazil nut

Omega 3s

I heard of hawthorn berry tea or liquid drops for palpitations theres videos on it and reviews on amazon claiming it helps with palps has anyone tried it???
