Some of the adrenal cases have really strong(bad) reactions to liposomal C. Maybe it's detoxing the adrenals too fast, who knows.
I would go back to the last known combination that worked best and then start your experiments carefully.
In theory if you eat animal protein then you're getting tyrosine, but maybe it's worth a try to take the amino acid just in case you're not breaking down proteins well. Tyrosine is the amino that thyroxin is built on.
Weak adrenals=weak t4>t3 conversion. Strong adrenals that come back online after a period of being down then trigger the need to support the thyroid side of things.
Also a few of the adrenal cases who had a rough time did well on Sugar after the adrenals and thyroid were in decent order. Don't forget the fuel once the engine is working. See Ray Peat for more info on Sugar and thyroid. Try some of his other stuff too like eliminate all pufa oils (only consume coconut and butterfat), some organ meats, high calorie diet with sugar, cream, lots of fruit calories and low/no veggies (anti nutrients). Some thyroid people do well on coconut oil. Have a look at guggulu.
Might as well try a super low dose of some natural thyroid too. But don't blame me if things go south.
If you have particular toxins that prevent t4>t3 conversion no amount of Iodine or co-supplements in the world will save you until you get rid of them so the above suggestion just might work.
Keep an eye out for other gallbladder symptoms, this stuck throat sounds very much like that to me.
