I'm on 100 mcg of Unithroid and 15 mg of Armour. I convert T4 to T3 just fine, so there's no real reason for me to increase the T3 levels.

At 2.9 it's no wonder you still have hypo symptoms--although your T4 number (if it's free T4 and the range is .8 - 1.8) looks good. You should be aiming to get your TSH under 2. 1-1.5 is ideal--although some people don't feel well until it's really low. Armour generally has the effect of suppressing TSH so the fact that yours is far from that indicate you need a higher dosage.

What's your free T3 level? It's possible you need more T3 and that adding Cytomel to the Armour might be needed.
