i dont think drinking is hereditary. i think the guilt gene is herditary and drinking alcahol is directly entertwined with alcohol. i believe this because every guy in my family on  my dads side is a heay drinker and i think it is this feeling of guilt that makes them drink i  feel this guilt to even if i didnt do anything i still feel guilty about it.  i am going to try my best not to drink but the odds are against me.
