Getting back on track

I gained over the holidays. While I'm upset about the gain, I have to remember that I am 30 pounds less now than I was a year ago. I'm seeing a dietician in a week to go over my eating habits. I think I need to up the exercise and that will help tremendously. I would really like to get in a half hour of exercise every night. I also want to walk the dog every day (he deserves it).
