I tried it once, when my boyfriend, who had messed me around for months, didn’t come home, and a friend told me he’d gone to another girls house. Drank a bottle of vodka and a packet of painkillers. Ended up vomiting and passing out on the bathroom florr. Then he came home and shouted at me. We broke up not long after that.
It was scary that I was willing to do that just to teach him a lesson. And I will never ever do that again.
