II think that somehow T3 and T4 have an affinity with mercury and a dosage raise causes mercury to be taken out of the nervous system (I felt great) and the after a few hours to be redistributed (felt like crap).


I don't think you theory is accurate. I have seen from experience that the effects of thyroid supplementation lasts 3 days. During the 3 days after taking your thyroid supplement your hormone equilibrium is changed quite drastically, including that of your adrenal hormones.

I don't know what exactly is making you feel worse after those three days but it could be adrenal burnout from an excess of thyroid hormones. Taking thyroid hormones when you are adrenally fatigued can cause an aggravation of your adrenal symptoms. I know this from experience... I was trying to figure out what was wrong with me for years and decided to give some thyroid pills a shot. What ensued was the most horrifying experience of my life. I didn't even feel like I was dying, it was worse. You should exercise caution with thyroid supplementation if you have a feeling your adrenals are fatigued.

And as a last note mercury in the pituitary and/or hypothalamus causes the adrenals to function poorly.

-Good luck
