I started on Armour three weeks ago gradually building up to 1 1/2 grains. Before that I was on 100mcg of Levo and still had symptoms. My Vit D and iron are in range although still towards bottom. I feel MUCH better on Armour though am beginning to feel tired again and am getting dry lips, mouth and eyes again. How much Armour is 'normal'? Should I increase my dose again?
