Before starting I was afraid I will not feel ok, but gave it a try, and for now everything is alright. I am hungry but I just drink a lot of water and simply don't think about it. And it works. But it took me a few days to get used to it. Maybe you could try to endure hunger after 7pm for two days no matter what, and see if it would get easier.
For example today I went for a walk with a friend. We made a little break in a cafe on the river, but it turns out it is more of a restaurant. So people around me were eating pizza, fried chicken, burgers, ice cream... It was tempting, but I just thought to myself I will enjoy the food tomorrow. It won't go anywhere, I don't have to eat tonight. I ate enough pizzas and burgers in my lifetime, let's now appreciate vegetables and fruits. And that helps me. I am now really looking forward to breakfast and lunch, which I used to skip and overeat for dinner.
