Now I can relate to the purposeless excitement, and inappropriate or bizarre posturing - I'm told I do this most weekends - best of all I NEVER remember - I can only assume this is because of the psychomotor disturbance you mention as I MOST definitely suffer later on during the weekend from the stupor and  rigidity thing - this normally comes on about 4 or 5 am Sunday morning.
And I never knew I was Catatonic....see,  never too old or stupid to learn something new.
 

LOL.
