How to do it 😖

Had a doctors appointment on Thursday, I was 35+1. I was told to cut out all sugars for these final 5 weeks bc baby is perfect, healthy and at a good weight and growth. He said no soda all day every day, no cereal, no snacks. It’s Sunday and I clearly haven’t listened. I’ve cut out soda a while ago, but I can’t stop eating sugar. Every snack I have is sugar, literally. And it’s all I want. I went one day without sugar and I starved lol. How the hell do I stop eating sugar?!
