pain
"I have taken Levorphanol for 18-months.  This is the absolute best pain medication I have ever taken. I have Fibromyalgia, rheumatoid arthritis and severe lumbar-sacral issues that are too far gone for surgery to help.  This pain medicine has a half-life of 8  hours.  100% of pain is gone... it even relieves nerve pain.  All the pain relief without the foggy 'codone-head' that you get when you take any of the "codones".  It is relatively inexpensive also.  I totally 100% recommend this pain medicine for anyone with moderate to severe chronic pain."
