Hi Timmy - welcome
I think most of us have experienced nights of controlled drinking.
Sometimes these nights will come after a period of abstinence.
This is addiction at it's most insidious IMO, because we'll privilege these few nights over the hundreds of other nights where we did not have control.
Abstinence is not the same as control, and I think you realise that.
I
always ended up back in the same place when I drank, sometimes sooner sometimes later, but always.
If I drank like a 'normal' person one night it was mostly down to luck.
I don't know you at all, so I can't say - but maybe you spun the roulette wheel and you had a lucky night too?
