Dar, I can't offer any help or insight into your problem, but I have the same experience. About 20 minutes or half an hour after taking my medication, I experience increased stiffness in my neck and shoulders. This lasts about half an hour. The stiffness is _not_ an end-of-dose phenomenon; it is a beginning of dose phenomenon, just as you described. My neurologist was reluctant to believe this, but I have charted the stiffness and the occurrences are predictable. The increased stiffness does not occur when I delay taking the next dose by an hour or more; it does occur when after I take the new dose.
