Hi Leesy, I'm new here too, and just quit yesterday (same as you). I too am feeling pretty okay, and am using the patch. One of the things for the car ride that I found helpful yesterday was 1.) remembering that it was just my brain that was telling me I wanted a cigarette, and I was not really craving nicotine-- because I had the patch on, and 2.) sucking on a lollypop. I also know someone who would drive with a pencil in thier fingers like a cigarette, just to get the feeling there. The one thing you have to steer clear from is rationalizing, and go automatically home. Stopping at a store is just going to make it more tempting!
Good luck! We're all in this together, and it also helps to just think about it as one day at at time. If you can get through today, that's a victory. Tomorrow is another day, with another set of hurdles to cross, and another victory at the end of it.
