There's a fine line between not obsessing and burying your head in the sand.
I think that when you're actively working to lose weight, especially if you don't have much left to lose, it can be extremely helpful to put the scale away for a while-- but then you're still actively monitoring yourself by recording what you eat and/or tracking and measuring progress in exercise. If you're hitting all your nutritional targets and slowly improving your workout performance, you don't really need the scale. You know that you're doing what's necessary for your health.
But the pitifully small amount of research that's been done on people who've lost weight and kept it off shows that almost all of them weigh themselves frequently (in most cases daily) during maintenance. It's one of the differences between those who lose and keep it off and those who lose but re-gain.
I think that people who have lost a significant amount of weight have had to get over the "not-what-I-wanted-to-see blues." It takes a year or more for most people to go from obese to normal weight, and in that time there are sure to have been times when the scale didn't move or went the wrong way for no good reason. You've also had time to figure out, "Oh, I gain two pounds every time I eat at Aunt Julie's, but it goes back down in a week."
I'm like one of the previous posters-- if I stop weighing myself, I'm able to pretend that everything's fine, and before I know it I've gained 5 pounds. So far I've always been able to get it back off, but I'm happier if i weigh every day so I only have to take off 1 pound instead.
