Hydromorphone
"Was diagnosed with three degenerative discs that have now compressed on top of each other at L-3, 4 & 5, creating horribly pinched nerves.  Started off with Vicodin, which helped for awhile.
In 2006 was switched to Dilaudid 2mg, then 4mg, currently taking 8mg/ 4 times daily.  Wow, what a great pain killer! With the Vicodin, it dulled the pain but with the dilaudid, it's completely gone.  Makes living life enjoyable again.  It's great not to be in constant pain anymore!"
