I adore chocolate but due to dietary restrictions can't eat sugar, salt and alcohol.. :-(
I try to find substitutes, like some ice creams with stevia or dried fruits.. But the chocolate with sugar - mainly dark - is amazing.. I' ll try the one you suggest although I had eaten one with 95% cocoa and was rather bitter..! Take care!
There's always an alternative to discover I guess, but I think what's the most important thing is to do the right thing by one's health. Well done and keep it up.
