I'm sorry you are going through so much at once.
I think everyone is different with steroids but I didn't have any problems on a 1 week oral taper. They recommend eating before taking it to avoid GI upset.
I've been on Copaxone for 5 years and feel it has been helpful. The shots aren't so bad if you keep in mind that they are your weapon against this nasty disease. Best of luck to you.
