What exactly in alcohol makes people addicted to it?

It provides dopamine to the brain. Also called the happy molecule. when people experience the feeling of alcohol, it provides their brain with dopamine. and after the brain experiences it once, it continues to want that feeling again

answer; i do believe the correct answer is (25) times faster;

if your boyfriend is cheating on you, my best advice to you is to dump him, he's only going to drag you down. and if you do, don't fret there's plenty better that know how to treat a person right. i mean honestly, the whole point of a romantic relationship is love, and if you love someone you aren't going to cheat on them. i do believe in second chances, but why would he cheat in the first place? i personally feel that if someone cheats, they ruin any chance they wanted/had with you. i wish you the best of luck with this, hang in there.
