Ozzy Osbourne is still feeling the effects of his drug abuse.

The former Black Sabbath frontman - who battled drink and drug addictions for the majority of his career - admitted he often experiences "wobblers" brought on by the LSD, also known as acid, he took during his wild times with the band.

Writing in his latest column in Rolling Stone magazine, he explained: "LSD is a great time until it isn't. One minute you're running down Miami Beach with a foam finger on your head, the next you're sticking a gun in your best friend's face.

"I still get the after-effects of LSD to this day - I call them my wobblers. In a flash, every little problem freaks me out and becomes the end of the world."

The 62-year-old rocker - who has three children with wife Sharon Osbourne and another three kids from his marriage to Thelma Riley - recently admitted his drug addictions nearly killed him, and he still thinks he is "living on borrowed time".

Ozzy said: "With the drugs, it nearly killed me on a daily basis - I did a lot of heavy drug taking for a long time and I survived it by the grace of God. You might not be as lucky as me - I'm living on borrowed time."
