If you barely have time to eat during the day, you may be coming home hungry. Then dinner is not enough. Try to keep meals evenly spread out throughout the day. Keep yogurt and baby carrots on hand at work, so if you do feel a pang, then grab a handful of carrots. Water throughout the evening, does help to curb the hunger if you've had your calorie quota for the day and you're still hungry. When I'm bored with water, I drink herbal tea.
If you're bored in the evening, try some activities that will keep you busy. I like Minnezota's idea of picking a messy hobby. You can also eat slowly, so dinnertime is prolonged a bit.
