I understand. The obsession is in your head, and you will learn to say "No" to yourself.
I had to lose 70 pounds. I had to go to the store alone every day. There are cookies, cakes, candy, ice cream, juice, potato chips, soda pop, pizzas etc etc on every aisle of every store. There are McDonalds, Wendys, Arbys, Papa Murphys, Olive Garden, TGIF, etc etc on every corner.
IF I wanted to lose 70 pounds, I had to learn to say "No" to myself on things that would defeat me. I do not like being beaten. Therefore I learned to say "No." I isn't easy, but it is possible.
Every time you say "No" you get stronger! Great job!
I lost that 70 pounds. It took me a year. That was in 2007-08. I've kept it off.
It can be done. Alcohol is even worse, because it will kill you and your family and your life - way faster than 70 extra pounds. Plus, I never had a hangover from pizza, never got arrested due to too many cupcakes, never wrecked a car after a double cheeseburger.
