I've been smoke free since Monday. Spending lots of time in novel environments without behavior-triggering events and people has made not smoking very easy. I've experienced only 2 or 3 real, hardcore cravings since Monday night.
This is also conclusion of week 1 of ski patrol. The job is very physical, with tasks that emulate one-legged squats, holding a shallow squat for several minutes, deadlifting, punching bags, and others, all with the additional cold-stress.
I anticipate that so long as I remain generally hydrated and I get enough sleep, this additional physical stress won't slow my training schedule and will also contribute to the 'toughness' aspect of training that can be hard to program for.
