I’m not a big drinker, but on occassion I can over do it with alcohol. Is it a mortal sin to drink to excess to the point where one is completely smashed? (ie, in such a state where one is at the point of passing out; unable to properly reason). There are gradations to drinking. It seems that there is a fine line to feeling slighly tipsy to becoming even more tipsy and lightheading to becoming drunk to becoming completely smashed. I realize that that drinking a few drinks cannot qualify as sinful, yet when does the act of overindulging in alcohol consumption become a sin (and possibly even a mortal one)?
