you found a place full of helpful individuals. Everyone has their views, but you will certainly find great information here. I know I have.
I am far from an expert, but I know it is normal to have problems with sleep while on solumedrol. The taper on pred would have the same effect except to a lesser extent. Those are powerful drugs that are supposed to give your body a real kick.
As fas as symptoms, from my experience... time my dear, time. And patience. You will probably go back to normal or close to normal. But it will take weeks or months. Be patient and take care of yourself in the meantime.
So, in a nutshell, yes, everything you are describing is normal.
