Thyroid question: Why did I feel worse adding T3?

[Guest guest]

I asked this on some of the thyroid boards and thought I'd post it here for a

different point of view:

My doc gave me some T3 to add to my T4 regimen.

I felt TERRIBLE! Had to quit.

Any ideas why this didn't work? Everything I've read says I should be doing

better on T4/T3 than on T4 alone.

I guessed that it was using more of my cortisol which is in low supply to begin

with.
