Well, I'm a big authority now that I've reached Day 6, but here's what I've learned. Drinking lots of water, eating fresh fruit, (both these things keep me from feeling hungry and thinking of a cigarette), wasabi-soy almonds (spicy enough to be distracting and it only takes a couple) and brain games. I have had a membership to lumosity.com for a year now. It does cost money (about 1/2 month's worth of cigarettes per year for me) but they offer a free trial period that may be enough to help someone through the first few days. And it's fun and (should I use this word?) addictive. That's my six days' worth of wisdom on the subject of getting through the early days of quitting.
