This is exactly my dad. Maybe 15 years ago, he and his two brothers planned a "brothers weekend". My dad stopped drinking cold turkey for this trip. One of the days they were together, my dad went through a horrible withdrawal- my one uncle found my dad on the floor passed out in his own vomit. He left him there to die! And he is a police officer. My other uncle finally came home to this and immediately called for help. He was hospitalized. There was another similar time when my sister went to see him and ended up in the hospital. He had no idea what was going on. He thought my cousin was there and was "talking to her". I luckily have never seem him this way in person although I did have some coffee with him when his hands were shaking really bad and he was trying to eat these cheese sticks that were way too hot.
