If I'm at home I do brush my teeth after meals. But I only mouthwash and floss for the morning (twice - once before shower, once before leaving home) and bedtime brushes.

I also brush my teeth every time I'm about to leave the house. Even if I've been home for half an hour and I haven't eaten anything. I'm so scared of my teeth going bad. I know it's irrational and actually counter productive because over brushing can cause problems.
