I forgot where we are in this thread so forgive me if I make no sense. I believe ANYTHING that gives you euphoria can be addicting and very hard to stop. For some people it's over eating, for some it's opiates, for some its whatever. If it gives you euphoria your gonna want more! The worst imho is methamphetamine and crack cocaine. They both release the most dopamine in your brain and create the highest euphoria. Next would be opiates.

Here's the real problem with such drugs and addictions and why they are so devastating and ruin so many lives. Your body will quickly develop a tolerance to the dose that got you euphoria so next time you will need more, and more and more and more. And that's what makes it so bad for any addiction that involves the release of dopamine, including binge eating. Without euphoria it's just a mental addiction or habit more then any thing.

You gotta know your limits and stay clear of stuff you know you will not be able to control or stop. For me it's opiates.
