The 30 Rock star struggled to control his love for booze as he rose to fame during the late 1990s and early 2000s, but it was only when he lost the love of his life, high school sweetheart Sabina, that he realised he needed to change his ways.
He tells Vibe.com, "What made me stop is when I woke up and my wife who I was with for 21 years, Sabina Morgan, left me. She wanted off the rollercoaster. And that was it. I thought I was winning because I was on TV, I had money but I lost."
Their divorce was finalised in 2009, although they had already been separated for eight years - but Morgan insists they share a very close relationship and they still say, "I love you."
He adds, "I love her, she's still my best friend. Nothing's changed - we still say I love you. Sabina still gets on my nerves sometimes, but that's my girl, that's my baby. So having gone through all of this - it's made me a better man, rather than just a funny man. I've always wanted to be a good man, a better man."
