DD, since it's probably not really working anyway, maybe you could speak to his doctor privately about decreasing the milligrams. That way, your hubby would be taking less, but not really realizing it. And, as I said, it needs to be decreased gradually anyway. Did he ever try melatonin?
Prednisone sent me over the edge, too, but that was 35 yrs. ago before I'd been diagnosed with hep C, and I only took 2 capsules. I had a psychotic reaction. One of the many, many possible side effects of this nasty med.
