Montel Williams opens up about stroke with warning to others

Montel Williams attends the "Going In Style" New York Premiere at SVA Theatre on March 30, 2017 in New York City.

(CNN)Montel Williams is happy to be alive, thankful for his wife, and glad he's a viewer of "The Dr. Oz Show."

The TV personality and host opened up to Robin Roberts on "Good Morning America" about a stroke that nearly claimed his life.
Williams was in New York City for work back in May when, while working out, a loud pop and realized he was starting to exhibit the symptoms of someone who'd just had a stroke -- including vision problems and drooling on one side of his mouth.
"Maybe about a month before, I was watching 'Dr. Oz' and I saw an episode on stroke," he said.
