Lmao people are insane on Reddit. 20s = I could drink mad dog 20/20, Id be hung over in the morning, maybe feel like shit into the afternoon 30s = I am not touching mad dog, if I drink a bottle of wine Ill def feel crappy in the morning but not for days lol. If your drinking more than yea its gonna be bad but Jesus, a normal over doing it, is not going to hang you over for more than a day unless you are out of shape af
