Don't know, Miller, but I'd just had some stress when the possibility of having Addison's came to light.
For nearly half a century, I've been on dyazide twice a day for HIGH b.p., suddenly started having low.
Did a bit of a web search before finding this board again, and found that usually Addison's doesn't come on suddenly, except with about 25% of people.
Good luck and do keep us posted. There's so much for all of us to learn from each other.
