Stay where you are: in the present.
Focusing on past regrets and loss,
or future fears and unknowns,
are surefire ways to relapse.
Continually bring your thoughts back to the present moment.
In this exact present moment as you read this, you can and are sober.
In this next moment, you can and are sober
and so on.
That is how it is done.
That is how all of us did it, and that is how you are doing it too.
