I can count how many years I've had a computer and been online by counting the inches on my butt.
Every night I tell myself I won't log on the next day until I get all my housework or shopping done. Every morning I tell myself I'll log on for a minute or two.. just long enough to enjoy a cup of coffee. (I know you're smiling because you know what comes next.)
The next thing I know hours (and HOURS) have gone by. I manage to rush around and tidy up enough to satisfy myself that the day wasn't a total loss.. but the inches keep adding up. I don't think even weight loss pills will help if I never get any exercise.
