I'm a light weight & sensitive to opiates, & my body breaks down morphine in pill form quite well. 15mgs twice a day keeps my back pain away......but first time I ever tried motphine, I got so sedated & my legs felt like jelly.
Morphine IME is the heaviest opiate I've tried......& for pain, I prefer it over any other opiate.
I didn't get into opiates for recreation, & to tell you the truth, I definitely wouldn't have started if it wasn't for the pain, but since I take them, they are fun some times.
Man, I noticed the sweating, etc just from several Opanas over 6 weeks, like I said, I can't even begin to imagine snorting 4 Opanas a day for a year, wowsers!
