... 800mg. 2x a day. I also take oxycodone 30mg. 3x a day, cymbalta 60mg., I have a plate in my neck on 4&5, dupreygens, ledderhosen, sjodgrens, and degenerated disc disease on lower lumbar. I need some input on a muscle relaxer. Have terrible spasms with connective tissue and cramps. All that pain works on your brain. Any books I can read?
