Well, simple carbs (which includes sugar) are highly addictive, so I can't say I'm surprised. Your brain was trying to get you your fix by convincing you that you were starving. In contrast, if you were truly starving you'd eat anything -- including lettuce ; )

So, maybe you already tried that, but there's a psychological/addiction angle that's seldom explored when it comes to simple carbs and obesity.

That said, if there's a drug that you can take that'll numb those cravings down to a healthy level, there's nothing wrong with that.
