On Friday, the Canadian rocker, 34, posted several photos of himself in a hospital bed. A few close-ups reveal large cuts and bruises on his arms, presumably from where doctors had taken his blood and inserted IVs.
The singer/guitarist explained on his website that years of alcohol abuse resulted in major damage to his liver and kidneys.
He wrote, "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 fiance 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."
Whibely must stay away from alcohol or he risks losing his life.
He added "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)."
Whibley plans on healing and then getting back to his music.
"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," he finished his post.
Whibley was once married to Canadian singer Avril Lavigne, whom he divorced in 2010.
