my boyfriend a very active alcoholic, with 8 years clean started drinking heavily on January 2014. I did everything I could to stop him. On April 25, he died at 53. I was detoxing him, he had been sober last drink on Thursday prior. He on that Saturday night at around 8 pm started seeing fire and flashing red lights. was very panicky but I had him sober. I got him in bed I went to my side, he sat up slid to the floor. I came around, his eyes were fixed pupils pinpoint, I started cpr, my first compression all this blood came out of his nostril and some brownish blood came out of his mouth. What do you think happened?
