Hi -- I just registered and have been following your postings with interest. I've had thyroid/adrenal dysfunction for years now and wanted to add a suggestion to what has already been written.
First, you should be aware that it takes about 6 weeks for thyroid supplementation to take full effect. Not that you cannot feel effects sooner, but the active hormone is something called a transcriptional activator - -in other words, thyroid hormone works in a lot of the body's tissues to help "turn on" other genes, and so it takes a while for the entire cascade to take place. Armor thyroid differs from the synthetic preps in that it is a combination of T4 and T3 (the synthetics are all T4). The body normally takes T4, which is produced by the thyroid gland, and converts it to T3. Many of us hypothyroid patients have trouble converting for some reason, so the T3 part of Armour really can help;. (An alternative is to supplement levoxyl or synthroid with a synthetic preparatin of T3, Cytomel.) So I'm a little surprised that on Armour, you weren't feeling some positive effects sooner than the predicted 6 weeks -- T3 is short-acting and quickly absorbed, and most people feel the effects of T3 supplementation more quickly than if they just take T4. This makes me wonder what else might be going on in your body to contribute to the crappy feelings.
I was there myself about 1.5 years ago, and here's what helped me. I realized that my diet was fairly heavy on the high-glycemic foods (I love bread, cereals, potatoes, etc.) and not very good on the fiber and protein end of things. So I modified my diet along the lines of the Perricone Prescription (more veggies, fruit, lots of fish, included a little protein with every meal) and noticed a PROFOUND change in the way I felt. For one thing, I stopped catching every cold that came my way. I also began to lose weight for the first time since becoming hypothyroid/adrenal deficient.
For the adrenal insufficiency, I took supplements containing pretty high doses of B5 and B6, and licorice root. It turns out that B5/B6 are crucial for the adrenal glands to perform their functions. This took a bit more time, but my adrenal levels went back to normal within about a year (and I felt CONSIDERABLY better long before that). I think there is a benefit to treating the body gently --your poor body has had a kind of rough time, and it might be good to allow it time to catch up to your meds before jumping into higher doses.
Finally, one of the best things I did was read a book by a doctor named Teitelbaum who is a chronic fatigue specialist (From Fatigued to Fantastic). I know it sounds like a hokey title, but this book has the most accurate information I've found on the many different facets of fatigue (including hormonal disruptions like thyroid and adrenal gland problems). He also has appendices in the back with information about how to find physicians in your area who are experts in handling these sorts of complex syndromes, and he has valuable advice about talking to your physician about what kinds of tests to run (lots of docs, as you probably know, are stuck in traditional modes of thinking and not really up on the latest research).
Anyway, sorry this has been kind of long, but I really hope some of it helps. I hope you can start feeling improvement soon.
