a combination of all 3 sounds good.  something you  could try is getting  hold  of  as many  dvd playing  devices  as possible, hooking them  all up to your tv, stock up on snacks and booze and  watch all the star wasr films  or LOTR films  back to back without  getting  up from the  sofa once. the a friend of  mine  did this  with the LOTR extended editions. he borrowed  a 6 disc dvd changer and a  projector and watched  all 6 discs back to back. all 12 hours  of them without getting  up once.  by the  time he was finished obviously he desperatly needed to pee. a  few days after he  had to  go to the  doctors because, apparently,  he  had caused damage to his bladder  from holding such a pressure  for so long... I'm  not  sure if i believe  that last bit  though...
