You should have been jittery. Probably on cloud 9. Your taking 4mg of dex. Plus a split dose so you are keeping your cortisol pumped to the top. 4 mg is equivlent to about 22-24mg prednisone. I saw in one of your messages you were taking 5mg prednisone. Thats about .75 of dex. You have not done yourself any favors. They prescribe 4mg for brain tumor inflammation.
