Oh, I know what you mean! I am not buying our Halloween candy until the 31st (even though it will be marked up to $12) and then I am going to buy the king size which I know I won't eat. the bite size candies are FAR more dangerous for me.
I got a tip at my weight watchers meeting about the "snack size" candies. Our meeting leader said to keep all of the wrappers next to the bag- that way you are keeping track with how many you are eating. the theory is that as you see the wrappers piling up, you are less likely to mindlessly munch. for me though, the more wrappers that i see simply means the more guilty I will feel as I continue to pop them in my mouth!
