I meant to say, start off with very small amounts, whatever you try. There's nothing more off putting than a great plate of food which you're never going to get through. To finish off a few morsels and clear your plate feels much better than leaving some.
I don't normally like chocolate, but when I'm recovering something like a Milky Way or even a Picnic, one small bite at a time, then put aside til you next fancy some, helps with the calories, which you desperately need.
