Until you have everything under control, have you tried weighing, measuring, and journaling everything you eat? The 'portions' I see on my plate are not always the portion size that I am supposed to be consuming. I think my eyes get bigger or else I "forget" that taste of this or bite of that as counting towards my caloric/carb intake. Try going back to writing down everythng you eat for a week and see if that does not help. I know it is boring and hard to do, but it is also effective.
