I agree with the previous post. Unless you happen upon a doctor with specific focus on addiction, their general training/experience is very limited in helping in this area. That's what I've found anyway. Either that or the dr might be in denial of some sort and turn a blind eye.
My spouse was having health and drinking issues a few years ago and we did the same, went to see the gp. He focused on the health symptoms and referred my H for further tests with specialists to rule things out. Much time elapsed before everything washed out, as if the doctor was willing to let time heal things or bring things to the fore.
The problem was, things had to be very, very bad for my dh to even think of seeing the dr in the first place, let alone make an appt and follow through on everything. One of the specialists didn't help things when he said, almost in passing when my dh told him it seemed that a drink in the evening helped the trembling he was having. The specialist said, "Oh yes, a drink is the best thing for this kind of thing."
I couldn't believe it! I was so shocked I was speechless, but did ask about his statement in a later appt for clarity. He was assuming no alcohol issues of course. And wasn't interested beyond the results of the tests he did to rule out other things.
I got myself to an Al-Anon meeting and found myself a sponsor and began seriously working the Steps. Then things began to change for the better for both of us and somehow dh began taking a more honest look at himself and listening to me, improving our communication. I'm taking care of myself and letting go what isn't mine. I'm amazed what's happening because I put the ball in my spouse's court and am no longer carrying it for him.
Anyway, that's my story, just to say we got little response from the doctors and they seem reluctant to be frank and upfront about addiction/alochol or else knew very little about it.
Wishing you all the best,
