I can understand you as i had been an alcoholic myself. I had indulged in both light, moderate and heavy drinking in the past. By God's grace, better sense prevailed within me and i was able to overcome.
Alcoholic drinking is not a sin but could turn out harmful to health if taken in excess. Jesus said what goes into the stomach does not defile us, but what goes into our hearts can defile us. So, Jesus urges us to keep our hearts from any kind of defilement.
Moderate alcoholic drinking is allowed in the Bible but heavy drinking is discouraged. There is however an instance when people indulged in heavy drinking i.e during the Marriage of Jesus Christ's relative at Cana of Galilee. Jesus did not condemn them at that time. There are also instances throughout the Old Testament when people used to drink Alcoholic Drinks.
There are people who take a few pegs of alcohol in order to keep their bodies warm when living in cold climatic places.
Proverbs 31:6 advises strong alcoholic drink to those who are of heavy hearts and to those who are nearing their death so that they may be strong-hearted and can boldly face their death. It would not be considered as a sin for such people.
Alcoholic drinks can be taken as per Doctors suggestion as a medicine. For example in case of patients who have heart-blocks. A christian Man of God, whom i knew very well, was advised by his Doctor to have a few pegs of alcohol as he had blocks in his heart.
Scientific Research has come up with observations that Moderate alcoholic drinking is good for health whereas heavy alcoholic drinking is harmful for health. But, how many of us can exercise such strong self-control of drinking alcohol moderately. The Moderate alcoholic drinkers can slowly end up as Heavy alcoholic drinkers.

If we have learnt that we are addicted to heavy alcoholic drinking then it is better we strive to leave it altogether before it can damage our health.
The best way is to stop it suddenly and immediately and cling to God, and our fellow-believers for help, encouragement and strength.
Taking our Spiritual Growth as Top Priority and our alcoholic drinking as the Least Priority can help us to overcome our Alcoholic Drinking addiction.
Where there is a Will, there is a Way. If we are committed to leave Alcoholic Drinking then it is possible to leave it either immediately (which is the best and safest) or slowly over a period of time (which is risky). We can seek God earnestly in prayer and God will help us in overcoming this addiction.
This is my honest personal opinion.
