Awal...I agree with what Trailmix just posted.....
To the alcoholic....alcohol is what enables them to function...it feels like air and water to them...to think of functioning without it...feels like death to them....It not only feels like "normal" behavior to them...it feels like NECESSARY behavior, to them...…In fact, at a certain point, the alcoholic requires alcohol in order to just feel "normal".....Addiction, is , indeed a powerful force, within an individual...
Having nothing to do with you...but, a "craving" feeling from within their brain....
To better understand this at the organic level.....google "dopamine and the alcoholic brain"....
