Though I'm usually more the savory person, I admit that when I write I eat sweets and chocolate. I'm sure many do that, even without writing. The weird thing is the how.
When I'm not working on my novel, I have the weird habit to eat colour-orientated. Let's say I've got a hand full of Smarties, I eat all the colours first that seem to dominate until I have two of each colour left, two yellow, two red, two blue, etc. Then I eat from yellow to blue, it has to be in this order. I can't just jump pink. I almost never break this rule.
AOAM stripes. I eat all flavours in order until I have only three of each left. Then I go for taste. My favourites will be kept until the end. Raspberry and orange if you must know.
Such a behaviour has almost autistic quality or maybe I'm just plain weird. A side note, though: I'm not eating it all in one go or even one day. This goes on for several days.
For all you chocolate and sweets lovers out there: you are not alone. And if it helps to get your manuscript finished.....
