My dad drinks at least 60 cans of beer a week (i.e., more than a six-pack a day). At 64, he has a pace maker, has had vascular surgery of some kind (not sure if it was a by-pass), and is currently taking Cardizem (and others). He retired two years ago and has not really found anything to occupy his time during the day, which contributes to his drinking. Now that I am home from college, I have noticed that his frequent mood swings are getting worse by the day and his reasoning skills and memory are definitely not as sharp as they could be. Is there anything I can do to get my dad to change his ways, or is he in charge of his own destiny? It's really taking a toll on my mom in particular, since he tends to take out his frustration on her. What should I do? Your responses are very much appreciated.
