Weight Loss: What to do about chocolate?

So I’ve been not too bad about cutting out the fizzy drinks. I still have the odd one but I find I don’t really enjoy it as much as I build it up in my head.
Chocolate on the other hand is a real problem. I am unable to portion control my chocolate intake so the best thing to do would be go cold turkey, but then I end up on a complete binge of 1000-1500 calories of chocolate in the space of 20 mins.

So how do I deal with this? I’m not even sure how to start. I don’t really want to cut chocolate out, because I do love it, I enjoy it when I eat it. Clearly I enjoy it a little too much, but if I am unable to control myself when around it the sensible thing would be to remove it all together right? But that doesn’t work either. Unless I stop carrying money with me, I suppose that’s a good way, but then I don’t want to develop some weird unhealthy relationship with when I have money it means I can buy chocolate. ARGH!
