Wow, I almost could have written that first post myself!
My situation is such that I suffer from a very severe case of IBS (Irritable Bowel Syndrome). I just saw a nutritionist a couple of weeks ago, and she gave me information on a diet termed FODMAP where you're supposed to avoid certain carbs that are difficult to digest.
I won't go into that, but I will tell you that the leaflet I got includes a meal plan with the number of portions I should consume daily from each food group. I almost started crying when I read that one portion of 'goodies' is allowed every day! This could be 1 dl of ice cream, ½ dl of pudding, 4-5 pieces (20-25 g) of chocolate, or 6-8 (25 g) sweets. It's not much, but after hearing nothing but 'you must go cold turkey' advice before, too, it's a lot!
Mind you, I personally haven't been able to manage with just that - just the other day, I ate a whole box of meringue in one sitting.. Awful! I think it depends on the reason someone overeats. With me, it's totally an addiction and a way to cut off from my emotions, so emotional work is obviously needed to heal entirely. But maybe the permission to have
something every day will help you get your consumption down to a more moderate level

Good luck!
I've also noticed that when I
have been able to stay away from sweets for a while (like a month) I don't even feel like eating them anymore - until something really upsetting happens and I need my 'fix' again..
