Aww bless. How old is she? Mine is 19m and too early to potty train but it's something I'm starting to think about it. I just can't wait til it's over with!
As for your mini-binge - it's over now and you know it makes you feel crap so just remember that when you get the cravings for a binge again! I try and binge on things like SW 'twiglets' or soy nuts if I'm really wanting to sit and munch all night. That way, I still feel naughty and get the satisfaction from it but am not doing damage syns wise.
Your binge doesn't sound that bad to me! Chalk it up as a learning experience, use it as flexible syns and just get straight back on track, which I know you are. That's what keeps a lapse from becoming a relapse over and over again.
