I'm glad you're not giving up, but please don't keep putting yourself through this. I know how hard it is, but reach out to us before you smoke. That's why were here.
The REASON is that you mentally gave yourself permission to smoke. Without your brain approving it (or maybe encouraging it), it would not have happened.
Think about your thought process leading up to that permission. Figure out NOW how you can short circuit that process this time.
You DID help out your body by not smoking for 71 days and that is something to hang onto for a bit as you start in again!
