yes, just to everyone one elses posts, I think the only way to stop playing when you are addicted is admitting it. Once you admit it and you know you are, you should atleast try to stop. At the end of the day, most people after a certain time realise that whatthey are doing is wasting their lives away, i think any sane/bright person should be able to see that.
How you go about changing your life is all down to how you do things, and one thing may work for someone but it won't work for another.
In fact, I will use the example of smoking, quitting a video game that you enjoy, are good at and have a lot of fun on is like smoking to me, and although I don't smoke I know all the horror stories and how people say it is very hard to stop, however I have experienced similar things.
One thing I will say that I don't believe will work, certainly for me is allowing myself to modulate my own time. For a brief period sure, but in the end the game always seems to get to me.
For example, when I had my laptop 24/7 I would get on and do my homework, for the next day (the night before sort of thing) however it soon became a struggle and I was getting up early to do it, although I would generally find a way to do some decent homework and never not do it.
So, in my opinion, at least for me, and you may have similar/completely different experiences, the way I would stop/will have to stop is by force, for example having the computer taken away/ not having 1 at all.
I believe there are two types of people - people who don't get addicted to computer games and people who do.
I see people who get on with their homework and then go on the computer or maybe both at the same time but they do well at school because they have gotten on with it, and I also see people who can't regulate their time effectively and as a result do badly, which is a real shame....
thats my take
