You've made a great decision. The next few days will suck, no way around that, get yourself some candy, gum, sunflower seeds or fake herbal dip to help with the cravings. Drink lots of water and exercise can help as well.
It takes about 72 hours for your body to detox from the nicotine, from there on out it is a mental battle. One that this site and your quit brothers can help you win one day at a time. If you haven't already check out the welcome center, it's the pinkish link at the top of the page. Find your new February group and post roll with them, don't worry if you screw it up the first couple times, they'll help you get the hang of it!
Check your inbox for a message with my phone number, text me if you need anything or just need to vent. It won't be easy, but I can promise you that it will be worth it.
Proud to quit with you today!
