I'm still struggling with my T3/T4 dose. I was on 10 mcg. T3 and 50 mcg T4 twice a day but GP upped the T3 to 20 mcg. each time. The high level of T3 all at once made my dizzy as a coot so I reverted to the original dose. now the throat feels sore and swallowing is difficult. Which would be best to up T3 or T4?
