Drug use and internal conflict eventually led to the band’s breakup. Negron’s offstage battles were intense. After years of addiction, he achieved sobriety in 1991, a turning point that reshaped his life. He went on to release seven solo albums, tour for decades, and share his story in his memoir Three Dog Nightmare.

Even as COPD affected his health, he continued performing until the pandemic.Late in life, Negron reconciled with former bandmate Danny Hutton, and family remained central to him. He is survived by his wife, Ami, and five children. His voice—raw, soulful, and honest—remains a lasting part of rock history.
