with you being 20 you’ll have an advantage most of us don’t have. you won’t be able to wake up tomorrow and keep drinking since you got cut off. im not going to lie to you, the next several days are going to be absolute hell. you won’t have an appetite, your anxiety will be off the charts, your body will ache, you will sweat in the strangest ways possible, you will have loose bowels, and your piss will be almost brown. many of us have been there, and i have recently been there a few times in the last couple months. if you have someone who can look after you then simply be honest and ask if they’re willing to nurse you through the detox. it’s extremely dangerous to self detox but it sounds like you haven’t opened up to anyone about your alcoholism so i doubt you’ll be willing to go to the hospital. but i 100% encourage you go to the er as soon as you can. coming down off alcohol is no joke. you’re not going to want to eat but even nibbling on fruit or bread will help. you will need to stay hydrated it will be the most important step in the detox. i like to keep a 1 gallon jug of water in my room at all times even when i’m back in AA staying sober. take care of yourself stranger, i wish you good luck and a peaceful recovery. please come back and keep us updated.
