Los Angeles - Whitney Houston's death made Mary J Blige quit alcohol.
The Be Without You songstress says her close pal's death in February 2012 had such a profound effect on her she began contemplating her own mortality and gave up drinking in a bid to boost her health.
She said: "I was at her funeral [and] being that close to someone you loved so dearly, in a coffin, it freaked me out. It made me realise the importance of my own life.
"I didn't stop overnight, it was a process. I feel great right now. I have more clarity, more focus, more patience. And I lost weight. When you stop drinking it flies off!"
'Trials and tribulations'
The 42-year-old star will even abstain from toasting her 10-year anniversary with husband Kendu Isaacs with a glass of champagne next year.
She told The Guardian newspaper: "I'll have a glass of ginger ale. Ginger ale and Diet Coke are my drinks."
The No More Drama hitmaker, who was hit with a $3.4m tax lien earlier this year, says there are always obstacles in life, but she has learned to deal with whatever may come her way.
She explained: "There's always drama, but you have to learn to navigate your way through it. Life is full of trials and tribulations, but I know now how to get out of it. You have to make a decision to say 'no more'."
