WOD as he is going to uni' soon I would leave him to sort himself out, once there he will do what all the others do which is going to bed too late and sleep in until he wakes from noise out in the corridor (assume he is in halls for the first year). If he is not willing to get up and earn money he is getting it too easily from some source, either you or manofdulwich, if it stopped he might be more willing to work to fund his dope habit independently. My eldest couldn't get to bed or get up, now she works full-time she is sooo knackered she flops into bed without hesitation.
