This is true -- and one of the reasons why checking the free values of T3
and T4 are useful, in case it's one of those "oh, synthetic T4 doesn't get
turned into T3 properly" cases. (There may still be other thyroid hormones
that are not being supplied, that desiccated thyroid might, so adequate
free T3 doesn't mean one might not do better on desiccated stuff -- but it
might suggest checking for other possible causes, too.)

If one does go on desiccated thyroid, one pretty much has to toss TSH out
the window, I hear, and dose according to FT3 and FT4 (free T3 and free
T4) instead -- TSH becomes very depressed, while FT3 and FT4 are in normal
ranges. For the synthetic stuff, TSH is usually a sufficient guide to the
necessary dose. If you add synthetic T3 (brand name Cytomel in the US),
then TSH may become unreliable as a guide in that case, too; best to test
both FT3 and TSH till one determines whether TSH alone is adequate.

Might be worth checking out thyroid.livejournal.com if you can; there are
some folks there who have a fair bit of data on the whole thyroid thing,
and you can get more detailed if reasonable.

Oh, ugh. Can you get an endocrinologist, maybe? If the current doctor is
okay for everything else, then a referral to a specialist may be less
daunting than a Whole New Doctor. And you can start out by insisting on
the numbers from a new doctor, if you think the old one would dig in his
