If your drinking is out of control and you plan to drink one drink and end up drinking five, that might be a sign.

The third C is craving. When you're at dinner with your kids or you're giving a presentation at work and you're craving alcohol, again, that could be a sign that you have the disease of alcoholism.

The other C is consequences. If drinking alcohol is leading to negative consequences for your physical health, your mental health, your social health, your job, that's another sign.

There's a spectrum of treatments, so on one hand people can get better on their own without professional help, but many people find a lot of help in things like AA or Smart Recovery. These are support groups. There are also drug and alcohol counselors, addiction specialists and professionals, psychiatrists who specialize in addiction, especially if there's a mental health issue that's driving the alcoholism, which is really common.
