Sometimes things just happen. Too many snacks might make some people start to reincarborate (if that's a word) and once there they could be a bit ruder once the hunger kicks in. I probably am a bit like the OP when I have too many snacks.

When you break your diet and you start to enter the world of carb burn your moods can swing quite a lot. At least mine do. When you just break that border into the carbs, you feel the worst hunger. Carbs hurt the most when you have just some and when you have too many. If you have some, your body craves more. If you have too many, for me its like an overdose. When really in LC, you have just a touch which doesn't affect your mood. The other area is when you have enough carbs to quench your hunger for a short time yet not so much as to wear you down. That's not a bad place to be but it's hard to stay there and lose weight. JMO
