Hi all, I have been reducing pred slowly and am now down to 4.5, so far with little or no side effects. I'm just wondering how soon and how will I know if adrenals have kicked in? I started 4.5 only this week and after cutting the grass yesterday I had pain in back like I was being crushed, shortness of breath and perspiring profusely, (that was probably due to the heat). Anyway, last week I decorated hallway and was fine but yesterday I wasn't too good at all. So was the pain/fatigue/breathlessness due to recent reduction or something else? I'm fine today.
