I know you are desperate for sleep, and sometimes sleep may be more important than taking thyroid
You're talking 5, 6, maybe 7 days before you can
consult your doctor. That's a ways off. Maybe cutting the dose in half for a day or two would be a safe way to experiment? If you could limp along on half a dose for a few days and get good sleep, it may be worth the trade off.
I don't understand Armour well enough to suggest you just stop taking it.
