I realise it's been a while since this thread was started. How are you doing now, T990?
Insomnia and restlessness were the worst side effects of prednisone for me. My doctor prescribed amitriptyline and it worked like magic. It's used to treat many other things too, but it's much better than other sleep meds because it's not addictive and you shouldn't become tolerant to its sedative effects, so you can take it long term and it will still be effective. And it will put almost everyone to sleep at a high enough dose (I started at a very low dose which didn't help, so my doctor told me to keep upping it until it knocked me out!). The only reason it may fail as a sleep med for some people is if the dose you need to sleep causes you other side effects that you can't tolerate. The forum has a support group for it here:

Before my doctor tried amitriptyline, I had tried every over-the-counter sleep med I could find, and a few other prescription ones as well. Nothing else helped at all. I had had no troubles sleeping before I took prednisone, but once on prednisone, the amount I slept steadily decreased until I was falling asleep well after midnight and waking, full of energy, at around five in the morning. Prednisone also made me so restive that I couldn't settle to doing anything and was hopelessly bored and restless all the time, which made all these extra hours awake unbearable. I know boredom doesn't sound terrible, but this was not like regular boredom. It drove me mad. After trying all the usual tips on sleeping and trying so many other meds, I wanted my doctor to prescribe some kind of benzodiazepine - these are the ones people are referring to when they warn about addiction to sleep meds. But before I even got a chance to mention it, the doctor brought up the subject and told me I couldn't have benzodiazepines because of the addiction issue, and because you build tolerance to them so quickly that even if they work at first, soon you will be unable to sleep again.
I am so glad my doctor prescribed amitriptyline instead. I really don't need another med addiction problem, and with amitriptyline I got an effective sleep med that's never stopped working, and - by sheer luck I guess - it also stopped the hopeless restlessness, and, after taking it a while, I realised it was working its antidepressant effects on me as well. It has a lot of potential side effects that you have to be very careful with, but I really don't think there's a better sleep med.
