Hello and thank you for your question.
I can certainly understand how frustrating this is for you, and also exhausting.
Yes, it would definitely be a good idea for him to see a psychologist for this addiction. I would probably start there, rather than a psychiatrist. It would be very common for the therapist to require that he NOT be drinking while in treatment etc.
Here is a list of therapists who also specialize in addictions, and you can do a search by zip code and insurance accepted etc. http://therapists.psychologytoday.com/rms/
Also, it could very helpful for your husband to attend AA meetings in the area for that ongoing human support. And for you, AL-Anon could really give you the support you need as this obviously a problem that affects you greatly as well. You don't want to have him become YOUR problem to fix and in doing so, you don't take care of yourself or your own needs, etc. A good book for you to read on how to be sure you are also taking care of yourself is called Codependent No More by Melodie Beattie and you can get that on amazon.com
So, yes at this point I would contact a psychologist and have him start therapy and get into local support group (such as AA) in addition. Please click ACCEPT button for this answer. I wish you the best... Thank you.
