Brandon Sanderson is a Twinborn, with DOUBLE SODIUM!
He has hidden this from the readers, did not include it in Mistborn, but Sodium is Allomantic! This is the truth behind his salt addiction! Burning sodium pushes creativity, and Feruchemical sodium stores IDEAS! He's been storing ideas in Sodium, then COMPOUNDING IT, burning the ideas to create a GIANT EXPLOSION OF AWESOME IDEAS! That is how he creates such brilliant stories!
You cannot dispute my logic.
Still skeptical? Consider this: He lives near the largest salt water lake in the western hemisphere. An endless supply of sodium.
I rest my case.
Edit: Yes, yes, I know it's sodium chloride. Shut up.
