The symptoms you're showing are classic. We call it the binge cycle. You can only maintain Atkins for a few days to a week and boom, off you fall. CAD sounds perfect for you. You don't have to get into the heavier cars but summer is the time for fruits. A lot of us CADers go lighter on carbs during the spring and summer (fruits/veggies) and heavier on them in winter (baked goods/starches/sweets). I think it's just the way we're made.
