I'm chocoholic myself. What I tend to do for a "fix", especially in the evening: hot (or cold) cocoa from scratch. I use what we call "real cocoa" (it doesn't dissolve in cold liquids + is used for baking, too). First it takes some time: making water boil, putting the cocoa powder into a mug, add a bit of sweetener (I use brown rock sugar), perhaps some spices. Then adding the water to it, stirring and adding milk ("real" milk - not this fat reduced UHT white water) - it not only helps because your brain is occupied with the work process but because it makes the whole thing a treat.

It's not like grabbing the chocolate which you tried to hide from yourself somewhere in the pantry - it's a reward for yourself because you're worth it. Consuming this with positive feelings instead of bad ones ("I shouldn't eat that - why can't I stop doing this") makes it more effective, more lasting :)
