The 'Jackass' star has been sober for 115 days but has recently been
suffering from mood swings and depression, so has entered the "looney bin".

The prankster - who last month was ordered to attend rehab for two years
after pleading guilty to cocaine possession - said:

"I've had horrible mood swings and severe depression. My brain is f***ed up from using so much
cocaine, ketamine, PCP, nitrous oxide, and all sorts of other drugs.

"My prescribed medication is not working so I'm back in the looney bin
trying to get that s**t right."

Steve-O - real name Stephen Glover - also warned others not to follow in his
footsteps.

He said: "Everyone's going to make their own decisions in life, but nobody
needs to make the same mistakes I made."

Steve-O was arrested in March on suspicion of vandalism and drug possession
at his Hollywood home after arguing with a neighbor about a fence.

He originally pleaded not guilty and, after admitting his actions during the
hearing at a Los Angeles court, will avoid jail.

Following his arrest, the MTV star was admitted to a mental health unit,
amid fears he was suicidal.
