Karl was frequently embarking on alcohol-free challenges and began exploring resources about the effects of alcohol on the brain and body. Realizing he had slipped into an addictive pattern, he gave up alcohol for good in February 2019. 

Karl and Bubble Hour host Jean went to high school together and have kept in touch via social media from afar. When Karl posted recently to acknowledge his new alcohol-free lifestyle, the pair had a lot to talk about!
