Actor Charlie Sheen, who is HIV positive, says he is amazed that he is still alive as he had taken a break from his medication for a bit out of curiosity.

Making some personal revelations, Sheen shared that he was curious to know what it would be like if he gives a miss to his medication for a while, reports eonline.com

"There's a host of side-effects that are manageable. I was just curious as I think a lot of people are. You know, you ingest something every day, and you feel a certain way.

"I just got curious about what I might feel like off this stuff. And then, if what was being professed, if any part of it was true, then I thought it was worth exploring,` Sheen said during an interview with Dr. Oz on Monday.

The 50-year-old actor opened up about his HIV diagnosis last year.

"I'm amazed that I'm actually alive. But I beat myself up from time to time about why it took me so long once I knew that I was HIV positive to really start embracing the whole physical package and the whole psychological package about bettering myself," he said.
