I feel your pain, its hard staying on track when your just starting out! I read an interesting article on sugar in the December issue of women's health magazine. It's not on the site yet but it said that when we eat sugary things like baked goods, cookies, cakes and what not it your body actually craves MORE food. It truly is an addiction! I find this to be really true, whenever I go off plan and eat something sugary after that I want to eat everything in site. It's sugars natural effect on our body, so all those cravings you have even after you had your first cupcake/cookie/pie etc are normal. It happens to all of us, try not to feel to bad.
The real challenge here is getting back on track! Take it one day at a time, promise yourself you will stay on track for one day. At the end of that day make another promise to yourself to stay on track just one more day. Before you know it you will be staying on track for weeks at a time. I found that if I stayed on track for 1-2 weeks straight my cravings for those sugary foods actually plummeted. I didn't feel the NEED to go to the store and get something tasty anymore.
Also take into account are you addicted to the food or the process of eating? I like eating. I don't even need to enjoy the food! I just like the whole ritual of eating. I took me a very long time to realize this and it's taking a long time to get over it as well but when I clued in that I was eating just to eat something clicked in my brain and it was easier to resist. If you feel the need to eat, go for a walk, drink a glass of water, go for a drive. Anything that keeps you out of that kitchen! A lot of the time dehydration can actually make you think your hungry so make sure your getting enough water!
You might also want to try a buddy system. It could be a friend, family member or even someone on here! Whenever you want to eat something off plan, talk to them first. Most cravings last 15mins so if you can keep yourself occupied for that long it could very well pass
Good luck! You can do this, you just have to get up, brush yourself off and move on
