I know how you feel. I struggle a lot with the emotional tie to food. And sometimes No S can feel really hard. I am actually returning to No S now after quite a long break from it. It was the only way I could control my intake and lose weight without feeling like I have a complicated diet or lots of rules or can't eat good food!
It sounds like you are pretty careful about what you eat. I mean, you knew you had exactly 30g of chocolate... I don't think you need to measure on No S!
However, if you have certain dietary needs, you may have to be a little more careful. Keep doing your four meals and see if your hunger starts to coincide with your meals. Also, if you always get hungry in the afternoon, I'm curious how many hours are between your lunch and dinner? I know when I have done No S in the past, I usually got hungry again between 4-5 hours later. But I usually ate breakfast at 8, lunch around 1, and dinner around 6. And I went to bed fairly early (maybe 10 or 11) because of classes/work in the morning.
Give it another try! Remember that this is about YOU. I have to moderate what I do somewhat as well, but I try not to have all-or-nothing thinking. Really, the way naturally thin people eat is by following their hunger. When they are legitimately hungry they eat, when they start getting full, they stop. But No S is for those of us who have trouble doing that because of emotional eating, bad habits, etc. So, if you are consistently hungry in the afternoon, maybe have your carb fourth meal then instead? Or have a light snack, just enough to tide you over til the next meal.
Don't give up!! Even if No S isn't for you, you will find a way. And remember to love yourself as is, life doesn't start X pounds from now.
