Methylpred DP and insomniac

I am an insomniac and this medicine has caused it to get worse. I have not slept since I started taking it and I am so tired but just can't sleep. I have had nausea, constipation, back pain, burning eyes and pain in my knees. I can't sit with my legs bent without have awful pain in my knees and when I lay with them straight they fall asleep. Has anyone had this problem? My heart races more then usual.

I have just taken my last dose and ever since I started it I haven't slept. I am so tired but just can't sleep. It's bad enough that I'm an insomniac anyway and this has just made it worse. I also have pain in my knees. If i sit with them bent they hurt and if i lay with them straight my legs start getting numb. Has anyone had this experience? My back aches all the time now. I have also had the constipation that goes along with it.
