In 2000 he was sent home from a continental cup competition in Innsbruck after a party at New Year's Eve, and later that year he was caught DUI with a 2.38‰ blood alcohol content. He was sentenced to 24 days in prison. In 2003 he fell into the ocean after he was fighting after some heavy drinking. His alcoholism was so bad that it caused Bystol to be kicked off of the ski jumping team in 2004 though he did fight his way back to the team.
In early 2009 he admitted to having tested positive for tetrahydrocannabinol. The sample was delivered in November 2008 in a Norwegian Cup race in Vikersund.
