My cousin died of Hep C waiting on a liver 2 years ago. He stopped using drugs in his 20's. He died when he was 42.
It catches up to you, one way or another, and let me tell you, it may have taken 2 decades, but it was still a very disgusting and horrible way to die. He had 3 sons. The oldest was 16. He was #1 in the state for a liver transplant. It didn't matter.
You know what I remember most about the funeral? He was so yellow, it was insane. The jaundice couldn't be covered up no matter how much makeup they used. And he was a really big guy, when he was alive. But that disease ate him up, turned him into a shriveled, tiny man that looked twice his age. THAT is what I remember. Because of some stupid drugs 20 YEARS ago.
