Sounds like my dad except instead of drinking hed added a 2nd pack of smokes and a nasty gambling habit
My father was a heavy drinker, heavy smoker (rolled his own cigarettes and also smoked pipes and cigars) and a big eater. He was 325 pounds when he died. All in the belly. He brought his heart attack onto himself, and sad to say, it was a blessing for my mother after he passed on. She wasn't as neurotic and was actually able to grow her fingernails and lost weight and ate healthier. I never really realized how unhappy she and dad were. They loved each other with a massive passion, but just had a lot of bad situations. Mom was always a person who tried to be careful with spending and saving and dad went through money like it grew on trees.
My brother has realized how much he had screwed up with his drinking and is doing so much better.
