I took DEX for myself. I had self diagnosed myself and I had Dex available. So I tried it and it worked in 4 hours. Dex stays in your system a little longer than Prednisone. About 20-22 hrs vs 8-10 of prednisone. Its also about 5 times stronger. Dex is still a corticosteroid just like prednisone. It replaces your natural cortisol production with a synthetic version. Dont be fooled that your doing better because of dosage. You will still have trouble getting below the taper point. If it was 5 of prednisone it will be .75 of Dex. I hit the taper wall at 1mg then just fought through it. When you say doing much better on DEX I assume your taking more that the 1mg. There is no difference in what it will do to your body. Here is chart.
