Morphine
chronic pain
"I've been on MS Contin for about 18 years for mult.chronic pain conditions .I take it responsibly and I consider it a huge responsibility to protect my health and my doctor's licenses. I had an odd side effect w/in 24 hrs of 1st dose. it gave me energy! I have also taken the immediate release 
.I don't find MSIR helpful(15 mg). also someone commented about a Avenza(sp?) ,the 24 hour rx..I was given rx several years ago (1 rx, one mo.cost approx.$1,200 ! I didn't find it
useful.Since'91been on patches 
,other narcotics etc.. but MSContin has been miracle rx giving me some quality of life..Grateful for any relief.God bless all who deal wuth thos pain issue "
