Okay, so 3 days smoke-free are in the books! The hardest part of the early stages of the quitting challenge is winding down to a quick close. Congratulations!
However, remember that cravings are going to keep hitting for another few weeks. Some people on the Facebook group report getting the return of huge cravings on day 9 or 13 or some random day. But these last 3 days were the most frequent and intensive ones that you'll have to deal with.
So just remember the tools that got you through the first 3 days and apply them as needed over the next few weeks!
