Hehehe, I am unemployed and looking for a job while playing Mr. Mom during the day, so my time ps pretty tied up... Hang in there.
Many people feel their best with Fre T3 and Free T4 at the high end of the renages, BUT it is better to aim for the middle and tweak up from there if needed.
Both shoudl ideally be at the same point in their respective ranges. Most people on Armour have higher T3 than T4, though. That's why I also take Unithroid--to get my Free T4 a little higher.
The lowest TSH can be is zero. Most doctors FREAK if they see a low TSH, but as long as Free T3 and FRee T4 stay in range, there is no risk. My TSH has to be less than .01 and even then, my Free T3 and Free T4 can be very low in the range.
The fact that you still have symptoms may just be that you aren't giving it wnough time. It can take months or even YEARS for all symptoms to resolve in extreme cases. Keep a symptoms journal and refer back to older entries every few months. You'll be amazed to find that you actually DO feel much better over time. It is just that the changes are so slow that we don't notice them from day to day.
You SHOULD get adrenals tested, but gettign adrenals tested is harder than talking a doc into testing Free T3. Good luck. I woudl suggest an 8am Cortisol level, then an ACTH Stim test. The book From Fatigued to Fantastic by Dr. Jacob Teitlebaum has advice on how to interpret the results on page 250 of the second printing (yellow cover rather than the older red cover).
I am not a doctor, nor have I ever played one on TV...
