On Thyroxine and still ill

I have been on Thyroxine for 6 years now after being diagnosed with Hypothyroidism and Hashimotos. My TSH level fluctuates every 3 months, as do my symptoms. I have read a lot about Armour and Synthyroid but mainly from people in the states. I have also been reading Mary Shomons newsletter on brand versus generic thyroid hormone. I am finding this all very overwhelming and would appreciate some feedback regarding these issues.
I would love to come off my thyroxine but my doctor has not even heard of natural, dessicated hormone and I can not find an endocrinologist to support a trial of Armour. I have changed my doctor/surgery three times. They all push for the generic thyroxine and I am aware of the financial interest. I feel trapped. Please help!
