Nice one, Paul!
My approach was not dissimilar in that the geek in me analysed the "why" of chocolate's appeal to me.
I liked the texture, the theobromine hit, the caffeine, the scent, but was not bothered by sweetness or lack of, had no issues with it being "naughty" or a "reward" or one in the eye for the Establishment (not saying the latter was yours, Paul, but it is a biggie for some of us).
Therefore in theory the Board recommendation for one or two squares of mega-dark chocolate per day would work for me. It probably would, but I haven't yet tried it, as for the moment - a "moment" lasting 2 and a bit years so far - not eating chocolate brings me the huge reward of a lot of weight lost (I was last this size in my early 30s) and therefore new or vastly altered clothes (it's a woman thing but new clothes I find very rewarding). Caffeine I get from good quality coffee plus some fabulous adaptogenic coffee that gives a real pleasure "hit" - not sure if I am allowed to name the make - which I drink black. Oddly, that fulfils the "scent" requirement as well. Texture - I love cream, butter, Greek yoghurt, natural fat that comes with meat, and all of those are fine on my T2-friendly diet.
So - that's me but it isn't everybody. Analysis is always my go-to, but again not for everybody. I may eat the 2 squares of dark chocolate in the future, or I may not. I hope this helps some of us.
