If there’s a silver lining to being a serial quitter, it’s that I know what’s coming on any particular day. I know from experience - and I’m reminding myself - that Day 3 is the day I get bored with quitting. Days 1-2 can be euphoric, or determined, or scared. But Day 3 is always either “okay, great, can I smoke again now?” or “this is boring, can we do something else now?”
Nothing for it but to shrug, acknowledge it, and keep moving forward. I wish I had advice for other quitters, but the best I can do is reassure you is that it happens, and to keep moving.
