By the mid-1990s, the stress of the constant filming and promotion of his films, as Van Damme explains, led him to develop a cocaine habit, on which he spent up to $10,000 a week, and consuming up to 10 grams per day by 1996. He was arrested for driving under the influence    in 1999.  Attempts at drug rehabilitation were unsuccessful, and he resorted to resolve his addiction via quitting cold turkey and exercise.  In 1998, he was diagnosed with bipolar disorder .     In 2011, he discussed the condition on the British reality show Jean-Claude Van Damme: Behind Closed Doors , saying, "Sometimes you're gonna like me, and sometimes you're gonna hate me. But what can I do? I'm not perfect ... I'm an extreme bipolar, and I'm taking medication for this ... When I was young, I was suffering those swing moods . In the morning, the sky was blue [when I was] going to school, and to me, the sky was black. I was so sad." 
Along came Universal Soldier, an action movie with a budget and buckets of blood, providing me with an 18 certificate movie which I was finally old enough to see at the cinema, as well as featuring sci-fi elements and two of my favourite action heroes. It's actually very difficult to express how much that all meant, but growing up with the Lethal Weapons, Predators and Terminators on video, unable to see them at the flicks, then finally being able to pass for 18 only to find that all the films being released in the early to mid-90s seemed to soften, even if they were part of a franchise, was terribly disappointing (one reason to be grateful for Alien 3 ).
