Unfortunately we all vary. This has been discussed before and people were all over the place in how long or how much it affected them. For me it lasts about 3 days for even a small oral dose, I’m talking 5 mg and I’ll go up over 300 Bg and it’s stubborn to come back down. When I had to get a steroid shot for an allergic response I asked for the bare minimum and I think it took about 3 days for that too. But I have heard it bothering some people for a couple of weeks. It gets scary because of the amount I had to use and then you don’t know when you are going to be “normal” again and drop too much.
But here’s that thread.
