It's because it's specifically advertised to diabetics and now you have it people automatically assume you must like it 'cause it's safe for you' it's all nonsense if you didn't like the 'good' stuff you won't like the sub-par substitute. Just continue to smile and be polite then either bin it after Christmas or give it to visitors but don't tell them it's diabetic chocolate and when they ask why it tastes different explain it's the diabetic stuff and your not too keen on it so your thinking of just giving it up then hopefully word of mouth will travel! Good luck and Merry Christmas!
