Ok, I can add something on-topic too :-)

Re: diet. My understanding is that for weight loss, diet is more important than exercise. Both together, of course, but diet is key. If you're trying to kick a regular chocolate habit (I love chocolate too. Who doesn't?), you might want to try very dark chocolate, and just a little every day or every other day. It has much less sugar and for me, doesn't spike a craving like regular sweet chocolate does. Cutting out sugar completely might be better and faster, but you're trying to do a lot of stuff at once, and there's usually only so much willpower to go around :-)
