Related to the question of "Is there anything I can do to help if he doesn’t want it," is the notion of an "intervention" or "rehab." In my experience, an intervention (loved ones confronting you) can be very powerful, but usually does not work right away...again, it plants the seed.
Rehab, for someone who doesn't want to be in rehab, is the same way. It's a very, very expensive intervention that has no more chance of working than a surprise group visit, if the person doesn't want to get sober, in my opinion. However, it does do a nice job of separating a person from their vice for a short amount of time. So, if you have someone who is at risk of OD'ing or something, then rehab can be a handy way of keeping them alive for 30 days longer.
If someone really wanted to do something drastic in their recovery to jump start it, in my experience an Oxford House is more effective than rehab (and it's free).
However, my experience and observation has led me to believe that all you really need to do is immerse yourself in a 12-step program and go to at least one meeting a day for 90 days (and still VERY frequently thereafter), get a sponsor and work ALL the steps with them, and calling your sponsor every day.
I used to wonder "how many meetings do you need to go to a week for the rest of your life?!?!" The answer changes for everyone. I've had periods of time where I felt the need to go every day, in periods of higher stress etc. I've also had days where I had to hit multiple meetings in a single day. In Covid, I stayed sober not going to a single in-person meeting for 1 year, but I was already 5+ years sober at that point....and it was still a very risky thing for me to do. These days, I usually go to 2 or 3 a week, and lead one a week. Sometimes more, sometimes less. They always, ALWAYS, make me feel better about life.
