After my first hospital stay I wasn't getting better, I was currently taking AsacolHD for my anti-inflammatory and they decided it wasn't working good/fast enough so they gave me Lialda to try. The next few days I began deteriorating very quickly. Terrible joint/muscle/stomach/intestinal pain, it was a significant increase, couldn't get out of bed by the 3rd day. BMs got worse, more often and more painful. They told me to go back to the AsacolHD. I ended up back in the hospital anyways, but have just continued taking Asacol (except for about
8 days in the hospital when they stopped carrying Asacol and were giving me Delzicol) and never had those symptoms again.
I believe your sleep issues are with the Pred, I suffer the same exact issues.
