"Everything I should have dealt with in the previous 10 years suddenly hit me in the face. There are some things I regret", said Wolstenholme at the time. "There are probably moments I should have enjoyed more than I did and that's a bit upsetting. With the mess I was in you don't feel any intense emotion any more".
Drummer Dom Howard said the band didn't realise there was a problem until they started counting how many drinks Chris got through on-stage.
"For some reason he could still play the bass, even though he was sh-tfaced", Dom told NME. "He was drinking on stage. I started counting how many drinks he was having during the set and I could see him getting more and more glazed. By the point we came off stage he'd be f--ked. It just got too weird".
Dom and frontman Matt Bellamy gave Chris an ultimatum "a few times", but ultimately stayed together.
Dom continued: "Chris now says things like, 'I can't believe they put up with me for 10 years'. Which is true. I can't believe we did. But we did. I've always believed in band integrity and sticking together".
