Como se fosse preciso, fica aqui o resumo:
"Symptoms of drinking too much
While all drinking has elements of long- and short-term risk, consistent drinking can lead to dependence and other alcohol-related problems. If you find it hard to stop drinking after you have started, you do things that are not normally expected of you because of your drinking, or you feel you sometimes need a drink in the morning, you may be showing signs of dependence and should consult your GP or a health practitioner.
Another sign of dependence is that, over time, greater amounts of alcohol are required to achieve intoxication. Persistent use and being preoccupied with your consumption, despite evidence of harm, is another sign your drinking might be unhealthily habitual.
If you feel guilty after drinking, have injured someone because of your drinking, or someone has suggested you reduce your drinking, you should also consider talking to someone about your alcohol consumption."
