I am maybe sensitive as well. I started Synthroid first so I was already used to the T4 by the time I started Armour...Starting the Synthroid was not good for me....I felt drugged. Took several weeks for me to be adjusted, but I hung in. When I stopped the Synthroid and started the Armour, well, the first two days were great...I guess the added T3...then I was back to feeling hypo soon after that. Now in the process of upping little by little. Every time I up so far, I do experience one or two unpleasant days and then back to my usual foggy self....it is going very slow for me...but for some much faster...but I still have a way to go yet...only on it for two weeks! But it sounds like you have a good plan, Karen. Keep us posted!
