Doctors told Thomas DeLorenzo he would have lived only two more days had he not come into the emergency room when he did in January 2001. He was dying of AIDS, they said, and his future was bleak because he had waited so long to get treated.

He was in denial for years after his partner died of AIDS in 1995. But after finally getting diagnosed six years later, he "did whatever the doctors said. Whatever it took," DeLorenzo, 49, of Los Angeles said.

"I remember the first day I took the medication," said DeLorenzo, who is now in law school. "It's this big moment that you say, 'Oh f---, here I am.' Reality just hits you in the face."
