What are the signs that a person has alcoholism?

Test yourself. There are several tests that may indicate whether you have a problem. The most common screening we use in medicine is the cage questions... ?have you ever felt you should cut down on your drinking? ?have people annoyed you by criticizing your drinking? ?have you ever felt bad or guilty about your drinking? ?have you ever taken a drink first thing in the morning (eye-opener).
Functioning. Impairment in functioning is the real key to a problem, as well as problems with one's family and relationships, problems on the job or with someone's work, marital problems, isolating and drinking alone, anger outbursts, alcohol withdrawal like shakes and tremors, drinking in the morning, history of duis, history of blackouts, problems with the law, spending too much on alcohol & health problems.
