Hi, and congratulations on 13 days now! Some of the things I do instead of smoking are:
Take a walk around my desk
Rearrange the things on my desk
Take a break outside (away from smokers' alley) and smell the air
Play farm games on my phone (an effective distraction that can be picked up and put down at any time)
Text a friend
Crochet or do any hobby that takes a little concentration
Read an in depth, hard to understand, technical discussion of anything you ever wanted to learn (I choose things about computers or psychiatric disorders, but I'm weird, I admit it)
Chew gum and tackle the never ending pile of papers that needs shredding
Turn on the Radio or iTunes or Pandora or put in your favorite CD and let it rip loudly (and then sing and dance until the crave passes away into that great dark cloud of smoke that isn't in your lungs anymore)
Check in here; read and post help for others
Just a short list, I'm sure you can think of many more. Hang in there and just don't smoke. Perhaps it's time to let go of that eCig, too? I think that just sets up the craving for more, unless you're doing no nicotine vaping, which I have heard also has some side effects because of no regulations on what they can put in them; but that's another topic for another day.
