When i suspected low adrenal function, i did this test, and my pupils would not stay contracted and would fluctuate.
When i did this test the other day, they did not enlarge or fluctuate. I got this test from the Stopthethyroidmadness Website a couple of years ago. There is another one where you do temp laying down, then stand, and take temp, can't remember how to do exactly.
On your post you made an error i think.
"Norepinephrine contracts the pupils and acetylcholine contracts them. "
