yeah no big deal you learned soemthing just dust yourself off and get back on the sober bandwagon. I'd try not to dwell on the relapse.
It does stink tho like yeah how come i cant drink like a normie. i used to like really dwell on that looking for that big EUREKA kinda meaning that would somehow enable me to drink like a normie. When the reality is the answer is simple I cant drink like a normie becuase i'm an alcoholic. theres really nothing further to investigate as to why at all. It just is what it is.
You've done well so far just keep charging forward.
