Tramadol
"I used Ultram for 3 years for chronic back pain/sciatica. It's the only medicine that relieved the pain every time. I took 1-3 50mg pills per day and NEVER had to increase dosage. HOWEVER, I started having memory/attention problems, shaking, blurry vision and possible seizures (being evaluated now). 
I've been off Ultram for nearly a month now and it feels like the veil has been lifted... like my brain's back, clarity. But my original pain feels twice as bad, I have restless legs syndrome and am sleeping MAYBE 4 hours per night. All are symptoms of withdrawal. It worked great for the pain.
