If you feel you have a problem do seek help. You may feel that you will never be able to control the alcohol or even admit you have a problem, but the problem will get progressively worse if you do not face up to it. It is a fact that other people have asked for help and found the situation can be resolved. If you DO want to stop, there is help available. Contact your local Alcohol Advisory Centre, who will be able to give you information and counselling if requested, and can also give information about other helping agencies eg.
Counselling is a kind of help.
It provides an opportunity for you to talk things through with someone who will listen to you carefully and sympathetically, and who will not judge you in thinking of ways to solve your problems or to live with them. Talk to the person you're worried about. Find a time when they're sober and when you're both reasonably calm. Tell them about the problems their drinking is causing. Listen to them.
