Obviously there is the AA website but it has two problems in my view.
First, a lot of people perceive them as "over-diagnosing." In other words, the test they suggest classifies a lot of people as potential problem drinkers. This comes from a laudable aim - better to include too many than to miss someone who really IS in need of help - but it does make the test quite easy to dismiss if you are in denial.
The other problem, of course, is that most people don't (or won't) visit Alcoholics anonymous unless they already think they have a problem.
A couple of rule of thumb tests that might help:
If your drinking costs more than money - think!
If you drink, and bad things happen, yet you nevertheless drink again, perhaps it is time to assess why.
Does your husband tend to put drink above things that rationally should matter more? E.g. does he cock things up around you and your children because he has drunk? Has he ever endangered you because of drink? When you ask him not to drink on a particular occasion does he do it all the same, thus putting drink before your feelings? And so on.
Lastly, a big clue is always in the answer to the question, "why do you drink so/too much?" If the answers are all negatives or not straight answers, e.g. "I don't drink as much as Jim"; "why shouldn't I drink so much?"; "what's it to do with you?"; "it's my money, I'll do what I like" instead of a straightforward answer to the question asked, e.g. "I like it" then that is in itself often a good indicator that he drinks too much for him because he feels the need to defend it.
If he asks what my qualifications are for saying all this, just say to him, "MIFLAW says you can't kid a kidder." He'll know what I mean.
Hope this helps.
