A crap St Patrick’s day then lol. Well that’s good and it shows he is dedicated. When he gets a month clean in, fingers crossed he does. And even longer. He will get tested out of the blue. For instance I was 2 month clean. I found a full bag of coke out side my car coming out the gym. That never happens. I ripped it open and binned it. My gf friend came round and pulled out 5 bags of it. 2 weeks before I seen a hypnotist, then I relapsed. We bump in to people we normally never would and then end up using.
He might already know this, but just make him aware of these things when he gets a good month in, even months. He needs to be mentally prepared for these situations and have the strength just to walk away, straight away and not dwell on it.
Things like.. I can have 1 sip I’m cured now, even if its 6 month down the line. That won’t work. He will be back on it for years if that happens. Its happened to so many people. Hope this helps.
