Realise that you may well be using it as a more entertaining, or safer substitute for real life, with its risks, problems, work, and boredom.
Set a sensible limit, such as 2 - 3 hrs, and use an alarm, or reminder in your PDA, or cell/mobile phone for 10 mns earlier, so you can finish. Have some things ready to do, then.
If you don't stick to this, no internet next day.
