Overcoming a life-disrupting computer addiction may be something you can do on your own, or it may require professional counseling. If you're ignoring your family, friends, self-grooming or other important facets of your life by spending too much time on the computer, the first thing you can try is to set a limit for yourself. Decide what you need and want to do on the computer the most, but set a reasonable limit that can fit into a well-balanced lifestyle for yourself.
A "reasonable limit" of computer time will differ depending on the person, but you should be able to enjoy a few hours of your favorite games, chat forums or whatever you like to do online without feeling compelled to keep doing these things over the limit you set. If you give yourself a daily limit, overcoming your computer addiction may be much easier, because when it's time to stop, you can remind yourself that you'll be able to continue again tomorrow.
Self-help by reading up on the field and its treatment could also help you overcome your life-disrupting addiction. One popular self-help method for overcoming a computer addiction is to start by gradually reducing your time online. For instance, you could just take an hour less from the time you currently spend on the Internet on the first day, and depending on how that works out, keep reducing your hours offline. If you can gain control of how much time you spend online in order to live a more balanced, healthy life, you may not need professional help for the problem.
If after setting time limits and trying to spend less total hours on the computer, you're still having trouble with an online addiction, it's advisable to seek professional help. Look for therapy options that don't consider computer addiction to be a joke, but instead recognize Internet addiction disorder (IAD). Since the whole concept of Internet addiction is fairly new, it may take you some time to find a qualified therapist with experience in that field.
After you do find some professional IAD treatment options, you should research and question the methods involved before agreeing to a particular therapy. For example, some therapists treat computer addiction with antidepressants, hypnosis or both, and these options may not be best for everyone who is spending too much time online. Especially since this area of compulsive disorders is new, don't rush into therapy without understanding whether or not a certain treatment is likely to be the best one for you.
