In alcohol poisoning what stages do you go through before it becomes fatal?

It's basically being: super drunk. When someone is highly intoxicated, they get central nervous system depression, starting out obtunded (very sleepy but can be roused), progressing to sleep from which they cannot be roused with normal interventions, followed by gradual slowing of respiration. If the alcohol level stays as high or rises, respirations slow further until the body doesnt get enough oxygen and heart stops
