I was on steroids for the best part of 18 months (on and off), and only really stopped them last August, they are horrid things. I lost my hair (it thinned incredibly badly), to the point I now have baby hairs coming through ten-fold, only in recent weeks which I'm delighted about :-)
Other than this, I also put on about a stone, I was swollen all over, felt really lousy, and the WORST thing ever was they made me unable to sleep (I'm normally a really heavy sleeper), this was honestly the worst, I was up for nights on end, and even now I take the odd Zopiclone on a Sunday to ensure that I get a decent nights sleep....
Good luck with them - they as I say are horrid drugs, but they helped clear my condition up along with taking immunosuppressant's alongside.
Instead of taking 32 tablets daily, I now only take 19 :-)))))))))
