I completely relate. I'm a student as well, although this is my 2nd time around (first career didn't survive the recession). I too feel good about my knowledge of healthy foods and what NOT to eat, but my portion control is non-existent. Once I realized I was eating three portions of cereal at a time, I got serious with FitDay.
If you need a cheerleader for your successes (or your slip-ups) just let me know!
