Chlorzoxazone
muscle spasm
"I am being weened off Vicodin ( for RA joint stiffness and pain) by my "pain doctor" because I consume alcohol and it shows in my urine sample.So  now I am not allowed my 10 year perfect solution for my RA/osteoarthritis joint pain with my 7.5/325 tablets prescribed 3x/day.I take one at 5:30 am before I walk 4.5 miles 6 days a week-it's like oiling my my joints.I often don't take the others during the day.BUT I know I have them for backup.So, he prescribed this chlorzoxazone at 500mg.The first morning I took it, after my walk I had to sit down and couldn't get up for 4 hours;I was confused,like a zombie,and wasn't normal 'til 5pm.The healthcare system is wrong, and I am another victim."
