I am like you, I get hungry at night but hay, slimming world is great, your points, calories or meals are not finished for the day so you can eat any time but just plan ahead.
Please don’t compare yourself to your friend, it is different. I tried CD before and I was so miserable and deprived all the time. This time I decided to do SW, because although it will take me longer , I will no longer be miserable or deprived.
The problem with quick fixes, they are not long term, and I have been yo-yoing for years for quick fix, if I spent that time on been more organised on SW and more imaginative with meal ideas, I would have reached my goal by now .
