Tried Flexeril off and on since being diagnosed and unfortunately it is just not strong enough for me. As I said to my doc today, I admit it, I am one tough case. I am just a walking, talking hard nut to crack when it comes to doctors to help me. After a while they just don't know what to do with me. It is like I am resistant to any med they try. I dunno....I always did say I have a constitution of a government mule.
