Yeah that happened to me too. I took the bait at five months and started back in with a certainty is just needed to 'reset' and was now OK.
This was born a year and a half long binge where everything got way worse and it was a huge struggle to return to sobriety.
This time - well over a year - I stayed the course and when those thoughts arose I took action.
For me, occasional thoughts like that come and go, but when they are persistent it is an indicator that I am not working at my sobriety enough. They call out that I need to exercise more or read the Big Book or journal about my gratitude for sobriety or revisit my step work or go to my therapist or reflect on the old reality of what drinking really brought to my life for so many years.
Sobriety needs our active support - lest we buy into that lie and find ourselves ever further down the hole.
