{Recovery} Can't Sleep!

Unfortunately, it seems as though I've gone from having a hard time staying a wake to having an impossible time falling asleep.  The last few days have been torture.  Bed, couch, wedge pillow, regular pillow, 1000 pillows - doesn't seem to matter - my back just kills and I can't get comfortable!  I basically stare at the wall or watch late night TV until 6 or 7 am, finally pass out from pure exhaustion and then sleep until lunch time.  I decided to pick up some Tylenol PM, but it didn't seem to help much.  I was able to fall asleep earlier, but woke up every two hours throughout the night.  I hope this gets better soon!
