Synthyroid often doesn´t work, you should know Armour or a mix of t4 and t3 is normally much more efficacious.
Just tell me ALL of your symptoms. Adrenal fatigue is pretty peculiar and you can know it by symptoms. For example often times I am hungry but eating doesn´t seem to alleviate that much and I seem to have to eat very frequently. This is probably related to my glucocorticoid defficieny.
