Morphine
"I have been taking Vicodin for near 20 years now due to chronic pain in my lower back and chronic pain & burning in my shoulders from Factory work.I have been on six 7.5 Vicoprofens  for a few years now. That amount works fine if I just sit around all day. If I want to take long hikes, Lift or move furniture, do extensive house cleaning then 6 is NOT enough and I was using 7 or 8 a day. Doctor wanted me to try Morphine ER 15MGs..2 a day  and try to get down to 3 Vs a day. A month into this trial period and I'm not liking the Morphine ER (and I've tried 300MG Tramadols & Butrans Patches) The morphine just leaves me feeling  sleepy, it just takes the edge off and like so many other medicines ,I have FLU like symptoms. If I had 10 mg pills that would work."
