I regained 21 pounds and started again without a countdown

I lost 36 lb over seven months a couple years ago, then let 21 of it come back during a rough stretch of work and family stuff. I restarted five weeks ago. This time I’m not doing a dramatic overhaul: Friday weigh-in, the same breakfast, a 20-minute walk after dinner, and one planned treat on Saturday. I’m down 6 lb, but the better sign is that I’m not white-knuckling every evening. I still miss grazing in front of the TV sometimes, and I’m practicing not turning one snack into a lost week. For people who’ve been through a regain: what made your second run feel sustainable instead of like punishment?
