Yes, you don't want to know how many times I've just sat pressing reload waiting for something to appear on the internet all night. When an App I was interested in for work was due, I spent almost 3 days hitting the refresh screen on my iPad.
I'm a little bit more in control now, but I have found myself addicted to a new game and putting in far too many hours. I do tend to have a pretty good bed-time routine now, up at 6-7am, work at 9, back at 6, family stuff and an hour space out before 9pm, interests till 0:00, then a bath till 1 (reading of course), then up to an hour or so of reading or interests, then bed. Getting to bed before 2:00 is an accomplishment and the closest I've had to a routine in all my life.
Jason.
