Hello,
I have gone carefully through your concern and understood your query!
Taking too much thyroid hormone can cause iatrogenic hyperthyroidism that is manifested with : increase in heart rate, weight loss, sweating, diarrhea ect.
The most serious side effect is takikardia that you should have had.
Fortunately, the symptoms are reversible.
It will take 4 weeks to turn back at the previous situation.
