Hey Nibbs,
I've done WW on and off for yonks now and I've found that as long as you stick to your points you
will lose, whenever you eat, whatever you eat. I guess that stuffing yourself before bed may not be overly good for sleep (or the next morning weigh-in

) and eating empty snacks rather than filling healthy foods will mean you may feel quite hungry rather than satisfied, but I honestly think that WW needs to fit in with you and if you like to snack in the evening and you have the points, then go for it! Personally I love snacks especially crisps and cereal but I have MASSIVE dinners (tons of veg) and because I have filling meals that are low in points I can afford the odd packet of crisps. Also as I've had a big filling dinner I don't need as many snacks, just something I fancy.
When's your weigh-in? Mine's on Wed where I'll see how my second week had gone!
Could you count certain snacks into the evening? Count them at the beginning of the day then work the rest of your meals around them?
I've found that when I need to stop (run out of points) that brushing my teeth really helps. I don't want to have to brush them again and it really does stop me snacking.
As for having a binge I do do this too, I like to feel full up and satisfied before I stop eating my tea. I know that lots of the current literature tells you to stop when you are satisfied but not full to bursting, but I've never been able to read those signals very well. This is why I love the old WW system, if I stick to my points I can eat what I like, simples. It's only my view though, others may feel differently, but it works for me!
