Go to an ER. Alcohol poison can result in DTs which can kill. I've had a seizure while going through withdrawl at home and laid awake in my bed wondering if he would awake to fine the love of his life dead beside him. I've also detoxed in a hospital and was told my potassium and magnesium levels were so low I was at risk of a heart attack and i'm only 30 and not overweight. I really hope you get to an ER. They are great and will take better care of you than you can alone. You can't start living a sober life if you're dead.
Oh, and welcome!
