pain
"I have always been very sensitive to medications and found after surgeries that the only one tolerated was Dilaudid.  Years of back pain, fibromyalgia and migraines were treated with ibuprofen and acetaminophen. I found I had cancer and the Dilaudid stopped working as soon as it started working, so my doctor suggested I try methadone.  I was surprised because I thought that was for heroin addicts.  I had no idea it was a pain reliever.  Now I can go 7 hours between doses and I don't feel nausea or high from it.  I now realize that people who use illegal drugs to relieve chronic pain should reconsider how methadone could save their lives."
