Sounds like you may be severely under medicated.
as on of the other post said, get the TSH, FREE T3, and FREE T4. With you being a Thyca patient, the TSH should be in the .0x range. The Free T3 should be between 85% and 100% of range. The way to calculate is subtract the bottom of the range from the top of the range, multiply by .85, and add back the bottom of the range. For you this is the minimum you should be. The Free T4 should be 65% of above. The best med for this is desiccated thyroid (Armour).
Also, have a 4 times in 24-hour saliva adrenal test done. If the cortical is low, the thyroid will have a hard time getting into the tissue.
Getting Armour and adrenal test and support will most likely be a hard 'fight'. Most docs have either been conned (via med schools selling out to the drug companies) or the doc has sold out to the drug companies.
They will deny it to the end, but the drug companies do not want your thyroid treated properly. They make more money selling you drugs to treat the symptoms of Hypothyroid.
