As a trainee, this is just the kind of situation I am keen to learn about.

I suspect that it would be a good idea to let you consider your preference and allow other to provide suggestions as to what chocolate bars could fulfil your snacking needs. You may decide that it was a momentary blip, and that you do, after all, crave a hazelnut in every bite and we could let you go back on Topic. Alternatively, we could ease your transition over to Toblerone - the duty-free shopper's choice - or a similar, though not necessarily equally triangular prismic, choice. If you were to lapse to Go-Ahead fly cemeteries then, well, maybe that's where I'd need my mentor's input.
