Raising daily thyroid med amount when starting any new thyroid med is important. Going
temporarily hyper if increasing to fast feels worse then being hypo, been there, done that. But, I can also look at my hyper experience, just as it was, experience knowing how I felt hyper. Now I know.
Going to the midrange and tying it there for a while is good for newbies, but if that doesnt work, then they must move on, weather it be thyroid, or other issues producing similar symptoms.
