Bonjour Lucas, I am Scottish living in Cognac to be near my daughters who married French men. I have vowed so many times never to eat anything containing sugar ever again, but invariably I do. It has taken me years to lose lbs because now and then I eat a bit of toast or a biscuit and the lbs gained then take ages to drop, but I will never give up. I wish you success in your quest to lose your excess. It is difficult but possible.
With regard to eating crap during the night could you try saying a word or phrase which would have you stop and think just for tonight I am not going to eat crap. A mantra which has helped me many times is saying the name of an old boyfriend whom I would hate to see me as being fat. Have a great lc day. 🌝
