The thing is...alcoholism (or whatever your addiction) is not some monster waiting to ambush you.
Every day you or I go sober, is another day we learned to cope with life without drinking or drugging.
I dealt with some pretty heavy stuff - breakups, moving house, illness, no money, family drama - and I didn't drink.
Some days were harder than others - but I leant on my friends here, I looked back at what happens when I drink...I did everything but give in and raise that glass to my lips...and I made it.
We have to vigilant, but we don't have to live in fear
I've found there are very few spontaneous relapses - if any. Talk about it as soon as you feel danger - get it out there.
You'll both be fine
