First of all, congrats on being smoke-free for two days!
I'm not sure if you have done this already, but you should make a list of the situations in which you generally have a cigarette -- ie. after meals, with a drink, etc. THEN you have to come up with an alternative action (ie. go for a walk around the block after dinner) OR avoid the situation all together (ie. giving up going out to bars -- or alcohol in general -- until you are over the worst part of the nicotine cravings).
If you miss the feeling of having something in your fingers, a stress ball can help (or even twirling a pen). Since many people put on weight when they stop smoking (they overeat in an effort to satiate their oral fixation), keep pre-cut, low-fat veggies in the fridge to snack on (low-fat/fat-free dip is ok IN MODERATION). Don't be surprised if things start to taste & smell differently -- smoking affects both of these senses, and as your system works out the toxins, these senses improve -- so don't season your food until you taste it in case you overdo it!
Oh, and get plenty of exercise to distract yourself.
As for "extra" things to do, how about:
- museums & galleries (see if they have any free days you can take advantage of)
- a controlled indoor sport if offered in your area (rock climbing or circus arts)
- an art class (a great way to keep your hands occupied while you have a creative outlet -- just don't make any ashtrays in pottery class
- volunteer work for a cause that is important to you
Good luck! Let us know how it goes!
