Canadian pop-punk band Sum 41 rose to international fame in the early 2000s, selling 30 million albums, winning multiple Junos and getting a Grammy nomination. Lead singer Deryck Whibley even became a staple in the gossip columns after briefly marrying Avril Lavigne.

But in more recent years, as the band's popularity plummeted, Whibley became better known for being unrecognizable after photos of his bloated face began circulating online last summer.

Now we know what happened.

On Friday night, May 16, Whibley posted a message to his website titled "Rock Bottom." Alongside photos of him in a hospital bed hooked up to IVs, he reveals that his years of "hard boozing...finally caught up to me."

As you can read below in his powerful post, Whibley collapsed unconscious and was rushed to hospital where it was discovered that his drinking had caused his liver and kidneys to "collapse."

His message ends on a positive note, but let this be a warning to all of us.

hey everyone, it’s deryck here. sorry i’ve been so m.i.a. lately, but i’ve been very sick in the hospital for a month and was pretty sick for a few weeks leading up to my trip to the hospital. the reason i got so sick is from all the hard boozing i’ve been doing over the years. it finally caught up to me. i was drinking hard every day. until one night. i was sitting at home, poured myself another drink around mid night and was about to watch a movie when all of a sudden i didn’t feel so good. i then collapsed to the ground unconscious. my fiancé got me rushed to the hospital where they put me into the intensive care unit. i was stuck with needles and i.v.’s all over. i was completely sedated the FIRST WEEK. when i finally woke up the next day i had no idea where i was. my mum and step dad were standing over me. i was so freaked out. my liver and kidney’s collapsed on me. needless to say it scared me straight. i finally realized i can’t drink anymore. if i have one drink the doc’s say i will die. i’m not preaching or anything but just always drink responsibly. i didn’t, and look where that got me. (i never thought i would ever say that! haha) anyway i have my passion and inspiration back for writing music. i already have a few song ideas for new songs. soon it will be time to start making an album and getting back to touring again. see you all sometime! there will be more posts again so say up to date friends.
