Good for you. I declared the 4th as my quit date even though it was 10pm when I smoked my last one. Dammit, it was before midnight, so that IS my quit date!
You can do it. You'll feel and smell so much better, I promise. I love being able to take deep breathes. I walk around all day doing it; it helps too because it makes ya kinda dizzy like a smoke does sometimes except it's much healthier.
