Naivety is nice, I wish I didn’t know what I know now. Because that would mean I hadn’t gone through all the crap I have 😉
Keep him busy, but not soo busy he has too much stress.
Not drinking will help too, alcohol will drop his guard. His conscious mind will not be fully in control if he drinks, and it would be easy to slip up. Unless you plan to watch him like a hawk if he has a few beers…. which is exhausting I can tell you.
Plus alcohol is a depressant, so that added to the fact he’s recovering so is potentially ‘down’ would be a recipe for disaster.
You’re doing well, keep smiling x
