I have a feeling it will be to do with you needing a drink - that's what makes you distracted - I have dealt with something similar and all I can say is, don't fall into the trap.
I prefer the term heavy drinker to alcoholic. Alcoholic is just the rest of society trying to put some distance between themselves and other bad drinkers.
Everyone who smokes is a smoker.
Some smoke more than others. We don't call 60/day people smoke addicts, we call them heavy smokers.
