Rod Stewart says he was "addicted to steroids" in the late '80s, which had some side effects.
“In those days we didn’t have in-ear monitors and the band kept getting louder and drunker, and I kept blowing my voice out. The steroids will take down the swelling in any membrane -- including your [penis] -- and it’s what you do when you’re in a bit of a pinch and need to do a show and you can’t sing.”
The steroids might have reduced the swelling in his pants, but they made him "fat and bloated" in other areas, caused him to lose sleep and gave him a bleeding ulcer. “One night, on stage in Sheffield, I thought I was in the kitchen with my mum because the steroids had eaten a hole in my stomach. I was bleeding internally and hallucinating. What the audience must have thought?”
Though he's no longer addicted, Rod says he has to take them at least once a year if he's "struggling," explaining that they "get you through the show, but you pay for it. You can’t sing for a week.”
Stewart starts a run of European dates on June 1st in Nottingham, England.

A Georgia man claims he has an original written draft of the top-secret recipe for Coca-Cola – and now he’s trying to sell it on eBay for $15 million.
Cliff Kluge says the document was in an old box of papers he purchased at an estate sale.
A spokesman for Coca-Cola says that while Kluge’s discovery might closely resemble the original formula – it can’t possibly be the real thing.
In case you were wondering, the primary ingredients were vanilla, lime juice, lemon oil, orange oil, cinnamon oil, and nutmeg oil.
NEW YORK (AP) - Guess this is why people call the fire department, not the police, to help rescue cats stuck in trees.
Officials in New York City say when a police officer tried to rescue a cat out of a tree in the borough of Queens, the officer needed to be rescued himself. The officer ended up getting caught in the tree and needed help to get back down to earth.
That ``help'' was provided by the Fire Department of New York _ who sent a bucket ladder to get both the man and cat down. As you might imagine, the New York Police Department has no comment on the story.
