try making a schedule and stick to that whatever happens..like fix some time for going to a particular site and also for posting there..and then do this for all your sites..we can always prevent time wastage by avoiding useless surfing..

i spend most of my time here sometimes coz i have to do post moderation also..but i have a fixed time for that and i visit only during that time and same i do for my blogs and other sites too..it takes time to get into a routine..but its not impossible buddy..
