When you quit, you body starts to heal itself right away but the nicotine addiction will try to trick you into a relapse.
You need to know what's comming next and know that it's just temporary.
"Smokers anonymous" if you wish, is the inetgral part of going through the process of becoming an ex-smoker.
Match with others who quit too, share experience and help out each other. It's anonymous, no annoying account creation steps.
