First off, Congrats Jade. Keep the streak alive, brother. I've got a buddy who had quit and went back to it.
Both older brothers (half brothers, same mom) are alcoholics. Oldest had issues with heroin, too. I don't "need" booze, and it has not interfered with work/life/relationships. Not predisposed to addiction and neither mom nor dad were drinkers.
As I've gotten older I prefer to have a couple, or get the little buzz going, and call it a night. Going too far always makes the next couple days rough... but when hanging with the fellas and having a good time, I'll overindulge a little.
