Most times I count, it's while doing something else useful that requires that I wait a bit at certain points. Other times I count when passing by the computer. Still other times while watching TV/movies on the other monitor or talking on the phone, or stopping for a snack. I don't feel it has the symptoms of addiction, which most importantly include a significant detriment to other facets of life. I still have good jobs/education/wife/non-computer hobbies/irl friends/etc, none of which is affected in a bad way due to counting. Addiction is when some other important part of life is hurt by the addiction. One might claim denial, which is often the first step of addiction, but I believe anyone that took a close examination at my day-to-day activity would see that there's no real problem here.
Don't forget to live before you die.
