Nobody was more surprised to learn that former Malcolm in the Middle star Frankie Muniz had a mini-stroke last Friday than the actor and musician himself.

"I consider myself to be very healthy," says Muniz, who spoke to PEOPLE from his Phoenix home Tuesday afternoon. "I'm home and trying to relax and get ready to get back to work. My biggest problem is I always want to be working, going non-stop. So it's a wakeup call to take a little time and relax a bit."

Muniz, 27, says after a morning workout he hopped on his motorcycle to pick up a few things at the home of his fiancée Elycia Marie Turnbow's mother across town. As he was driving, the vision in his right eye began to blur.

"I thought I had something on the visor of my helmet. I couldn't focus out of my right eye," he says. "By the time I got to her mom's house I pretty much had no vision in my right eye."

By the time Muniz got home from the short drive, he felt even worse.

"I was really dizzy and in a lot of pain in my whole body and my head. My hands were numb. I didn't really have good balance and I was almost dropping the bike. I never had this before. I was like 'What's going on?' " he says, baffled at how quickly the symptoms came on and then intensified. "I felt like I was getting stabbed in the head – the worst headache you could ever think of. I couldn't see anything."

Less Invincible

Turnbow was home when he arrived and tried to assess his condition. "But I was saying things and she said, 'You're not speaking English,' " Muniz says. "It was really weird."

Muniz, who plays drums for the band Kingsfoil, went to a Phoenix area hospital, where he was treated and released. He's resting and still under a doctor's care, but plans to head out on an eight-date Northeast tour with the band this weekend.

Though Muniz admits he eats "like a 7 to 10-year-old-kid," he lives a healthy lifestyle.

"I never in my life had a sip of alcohol or even touched a drug," he says. "I take a lot of pride in that."

But the incident did leave him shaken. "They say it is usually a warning of maybe what could happen in the future," says Muniz. "It's changed my mentality when I'm going to eat now. I feel a lot less invincible."
