For what it's worth, now that I am a low carber (more or less the SCD but without any of the higher carb items on that diet, hence no honey or almonds or fruit), I notice much less moonface for a given pred level then back in the days when I was a normal/hi-carber. Low carbing seems to reduce my UC symptoms by the way, though it is no wonder cure for me.
As far as moonface goes, I should probably cut back on salt too, but have been fairly normal on salt. Generally my moonface does go down as my pred level comes down, but maybe that is also due to the lower carb diet.
