could be, as you said, a flu type
in the morning, and 1/2
around noon is what I was suggesting. What happens when you take the whole dose at once, is that the T3 wears off after a few hours and you don't have enough left to get through the day.
You may, eventually, be able to increase to the 60 mg, taking 30 in the morning, and 30 later in the day, but not right now.
I have read some of STTM books; however, I have little faith in either the books or the website.
