Hi Nat... by my reckoning, you are now a non-smoker. I would throw out all of your remaining cigarettes, lighters, ashtrays, tobacco, etc... (if you haven't already).
Congratulations!
We are not going to lie and tell you that the next few weeks are going to be all rainbows and smiles - they could be hard. But, I bet that they won't be anywhere near as hard as you are expecting!
I'm not sure if you know about the SOS system here? It's saved a lot of quits when we are feeling vunerable - please, take time to read it here http://www.quittrain.com/topic/8-posting-an-sos/ and, posting your OWN reponse to your OWN SOS can be really helpful - you can do this here http://www.quittrain.com/topic/259-pre-respond-to-your-own-sos/ (I would highly recommend going through this entire thread, and see what everyone thinks will help them get past a crave!
Hmmm, what else... OK, a crave to want to smoke is only supposed to last a maximum of 3 minutes (although it can sometime seem like longer) - so start clock watching when you feel the need.
Your blood sugars are going to take a hit, so I suggest that you stock up on fruit juices and sweets/candy for emergencies. You are going to need to protect your quit no matter what - it is the most important thing in your life right now. Pre-warn your husband that you might be a bit grouchy for a little while, and I am sure that he will understand!
And finally... stay close to the board - people are here 24 hours, and we only have one goal - to make sure you succeed in your quit! (and have fun while doing it). Oh, and get a ticker! Mine really, really helped me in the early days! And treat yourself - make sure that you spoil yourself rotten to begin with - afterall, you are going to have loads of extra cash since you are not spending it on cancer sticks!
I am so very happy for you, and I cannot wait to watch you on your journey to freedom :)
