Addiction to anything is not a good habit. I also find it very addictive. I force myself to take time off of all gaming to give myself a break. I've gone off for a month at a time twice since September. Anything can be bad if it is done in excess. You have to decide for yourself "what is excess?". If you don't enjoy it, and still play, that is unhealthy. Only you can decide though. I might try taking a week or 2 off, and see how ya do. Also. Just because it's unhealthy for a friend, doesn't mean it's unhealthy for you.
