Cyclobenzaprine
"Have Lumbar tear lots of nerve damage but finally having nerves in back fused, etc. Went from a HIGH 10-7 to WOW 7-4, I have chronic severe PAIN & take 10mg NORCO 5 daily which doesn't relieve at all the constant SPASMS through out my body! You CAN'T SLEEP! body just spasms to where you just can't sleep! I tried a 10 mg cyclobenzaprine, this also knocks me out but WELL WORTH IT; this was the first time I slept for a straight 8hrs  since. I've been unable to find any medications to help till Christmas. I ran short on pain med & started taking 800 mg of ibuprofen (prescription) which is a MIRACLE I FEEL I'VE FINALLY FOUND THE PROPER MIXTURE & I'm able to say I've not been this alive since 2002!"
