Just weeks after undergoing a kidney transplant, George Lopez says he feels better than ever.
"It hasn't even been a month and I feel alive," the 44-year-old actor says in an interview on ABC's "Primetime Live," to air Thursday (10 p.m. ET). "I feel as good as I did bad, I mean it's unbelievable. Everything has changed. My personality has changed, my appetite has changed, my energy level has changed."
Lopez, star of the ABC comedy "George Lopez," had a genetic condition that caused kidney deterioration. Last month, he received a kidney donated by his wife, Ann.
"It was really bad," says Lopez. "I was operating on 18 percent kidney function in both kidneys and at 50 percent, you go onto dialysis."
"It's almost like, if you were buried alive and you were trying to dig yourself out," he says. "That's what it felt like, just everything was just a burden."
Still, Lopez says he never considered quitting his TV show, which has wrapped for the season.
"You can't quit," Lopez says. "I wasn't going to quit. You know, this is what I was made to do and I was going to do it and I wasn't going to stop until you know, it stopped me."
He co-stars in the film "The Adventures of Shark Boy & Lava Girl in 3-D," which opens June 10.
