Andy, it's a process--I think everyone has wobbly times in early sobriety
especially when we are in triggering situations.
I think getting out of the situation and going to your Mum's was a smart response.
All I can tell you is that as you don't let these situations derail you,
your "sober muscles" get stronger and the situations begin to lose their power.
The other thing that happened for me
was when not drinking
replaced drinking
as the "norm" of my life.
That will happen with time and work on recovery.
The idea of responding to a trigger with drinking has increasingly become
the more
uncomfortable option for me, which is the total reverse
of how it used to be and something I thought I'd never see.
I still have my moments, but they are less intense and more time between.
So take heart and keep slogging forward.
Life truly is better sober, but it takes awhile to get there and get
your emotions "retrained" to sober-as-norm
but it will happen
