Is Prednisone the devil in disguise???

New to transplant friends and 9 weeks new to a pancreas transplant.  After battling some serious medication side effects, it seems we have everything right but the prednisone.  It's making me crazy.  Outside of the mood swings, and my now round face, I have insomnia and hand tremors something fierce/  I was sent home on a split dose of 30 mg daily.  That was down to 10 mg daily in a split dose until I spiked a fever they couldn't find a reason for. . . .. they increased me to 20 mg daily in a split dose plus the 5 days of IV steroids I was getting every 4 hours in the hospital.  I don't get it?  What are these steroids doing?  All glucose and hormone levels have been normal - so why the increase, I don't know?  However, because numbers look good, docs don't seem to care if I sleep of if my hands shake so badly and I drop things constantly.  Their solution?  Don't split the dose and you might sleep.  Great idea. . . I took them all in the a.m. as instructed, and now at 5 p.m.  I shake even worse than the rest of the day.  GGGGrrrrr frustrating.  Funny thing _ I 'm a waitress and a substitute teacher. . . I went back to school today and discovered I needed a student to hand out papers because I shake that badly that I can't do it!  Any suggestions that I can pass to the docs?  Does anyne know how long you are normally on this devil drug?  Don't tell me forever.  I don't see the docs until the 25th, and am not leaving their office  until they do something about this.  Crazy lady who sleep 3 hours a night, and has awful mood swings, and shakes like a leaf can't LIVE this way.  I'll never get back to waitressing, and some sleep would be OH SO NICE.  Any suggestions or comments?
