When I started this I had a rule. No banned foods. I refuse to label food as "good or bad". To me I term them "helpful and unhelpful"
Chocolate, to me, falls in both camps. I like it. I really enjoy a chocolate and a cup of coffee after a long day, or at that time of the month. It's high calorie, so it's not helpful to my weight loss, however there are studies that show that good quality dark chocolate is a useful source of antioxidants - and it makes me happy
I plan for it, I count it, I eat it mindfully. No scoffing it down quickly, no apologies, no recriminations.
A lot of the chocolate subsitutions mentioned aren't available to me in the UK, and for a while I did try things like the low fat, low calorie chocolate drinks, but found that they didn't qwell my cravings, and left me feeling cheated.
So for me, it's the real thing, in moderation, providing I have the calorie room. I tend to have the 70% cocoa solids chocolate, as its pretty hard to binge on that! I love the Lindor balls too, I got a package of them for my birthday.
