Frankie Muniz suffered his second mini-stroke within a year on Monday.
"Almost a year to the day, I experienced another mini stroke. Hopefully that will be the last. Miserable," the Malcolm in the Middle star tweeted Tuesday.
Last year, Muniz was hospitalized for a mini-stroke, which he described as "not fun at all" and attributed to working too hard.
"Have to start taking care of my body! Getting old!" Muniz tweeted at the time, shortly before his 27th birthday.
