I think you're not addicted YET. but when you keep on drinking when you're bored and stressed I think you have a high chance to become addicted. Addiction seeps in, you start using the drugs, in this case alcohol, because ytou like it. then before you know you're doing it daily and it's the only thing that helps with boredom/stress. it'll turn into you feeling bored/stressed when you're not drinking, so you'll start drinking not to feel that

You also said you have no self control when you start drinking, so if you keep this in mind. try buying a smaller bottle, so that when you finished that amount you don't have anything in your house to get even drunker.
