I think if you start smelling like a pharmacy it is no longer okay. My last prednisone I took februari 2nd. All kind of trouble but so far, tests, tests and more tests, I am doing fine plus my organs are great (who ever thought that). They even gave me a ct scan and my brains are not damaged.
I would take antihistamine but since most drugs don't work I do not even bother to take it.
It was a good question. There are more addictions as one is aware of.
Good luck
