I quickly got the Moon Face which I understand is common on steroids. I hate it. Also I am already putting on weight. Went on the diet doctor web site which is good and gives details of a low carb diet which my rheumy recommended. I am on 50 mg of Pred and wonder if the moon face goes when the dose goes down and how quickly or is it a case of dieting to loose it. I am already overweight to start with and very weak willed. Doesn't help waking at 3 am and getting up as I tend to eat at 6 am and am then hungry at 10.30 ish. Seems a minor thing compared to other peoples problems.
