I also tend to have something nearby when I do serious writing. Lately I've become hooked on the "very berry" sour gummy worms. I've even gotten my writer daughter started on them. :-)
That said, I don't eat bag after bag. Especially since I'm working on getting healthier this year. But...a few, ever so often, with restraint, isn't so bad.
I also like plain m&ms...and those Brookside dark chocolates with the pomegranate centers. And the Hershey's almond things that come in a bag...
