We call that "Muskel-Kater" "Kater" means this kind of "stiffness" or a bad feeling in general (for example after having had too much party). A "Kater" is also a male cat. <img src="/ubbthreads/images/graemlins/winkwink.gif" alt="" />


We have the exact same expression on having drunk too much tbe previous night, "een kater".

It's one of these days...
