Sum 41 singer/songwriter/guitarist Deryck Whibley has spent the past month in a hospital.

Whibley took to his website to describe what he's been going through and he shared a few photos.  For years, Deryck Whibley has battled alcoholism.  Then, he collapsed and organs started shutting down.

He writes:

"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."

Whibley is only 34 years old.  He was married to Avril Lavigne from 2006 until 2010.
