I agree, its very individual. Also, I think it depends how long you were on the Pred. Last year January when I started Pred, I was only on it about
2 1/2 months. The side effects, including moon face and any extra fat disappeared pretty quickly once I got down under 10mg. Also the side effects weren't too bad except on the really high dose (above 20mg). But I did start shedding hair back then and it never stopped until I had to go back on the Pred a month after being off (for me I lose almost no hair, barely a strand, when on 12.5mg or above of Pred. Below that it comes out like mad until its all out of my body).
So this time, being back on Pred since last May (I was almost off in November though), the effects seem to be taking longer to go away. I'm also tapering very, very slowly right now so the effects of the taper don't see as severe this time. The hair shedding is happening now but not as extreme when I have a faster taper. Although I'm just down to 10mg now so we'll see if it picks up. I hope not as its very thin already.
