pain
"I was in the hospital a year and a half ago for heat exhaustion and rhabdomylosis.  The pain from my muscle deterioration was the worst of my life.  My doctor gave me Dilaudid. It definitely helped with the pain and made the most pleasant side effect of eliminating the addiction pangs from smoking. I had previously tried every other method that I could think of to quit. None worked for me.  After 4 days I was released and haven't smoked since. I think 4 days of hospital confinement with regular dosage of Dilaudid could help a lot of people quit smoking."
