I had a brief passion for cheap chocolate bars from Aldi, in the 1990s. Whole nut, and fruit and nut mostly. I'd break a huge bar up into large chunks, put it in the coldroom at work, and I'd keep going in there and grabbing a chunk to scoff. But after a week or two I started to feel like crap, and figured it was probably the vast amounts of choccie that was doing it, so I stopped.
These days I live in fear of a heart attack so I usually keep away from the stuff except for one (or sometimes two) of those tiny Hershel's "Kisses" blobs. I even worry about eating that amount, but there has to be a balance between fun and health. I should probably try making my own healthy, liquid chocolate by using cocoa, soya milk powder, fruit sugar, polyunsaturated oil, and maybe rose water to make it taste like Turkish Delight. But it would take a lot of trial-and-error and it'd probably be very messy. I'd have to learn about how to use emulsifiers to stop the aqueous and oily layers from separating out. I don't know how the manufacturers manage to get their chocolate so smooth.
