Nicholas Brendon has checked himself into rehab.

Brendon, who played Xander in Buffy, has announced on his official site that he has checked himself in for treatment for alcohol problems.

"After realizing that I had a disease that was taking control of my life, I decided that the best way for me to regain my health was to enter a treatment facility," Brendon states on the site.

"I'm grateful for the love and support I've gotten from my wife, Tressa, my entire family, my business associates, and my friends."

"Over the past eight years I've discovered that Buffy fans are the most caring and supportive fans in the world," Brendon added.

"Knowing that they will be behind me, rooting for me as I go through this process, makes everything that much easier. I'm looking forward to leading a happy, sober life."

Despite his popularity for the part of Xander, Brendon has failed to capitalise on that success post-Buffy.

Here at Cult, we wish him well.
