John Mayer revealed he gave up drinking after an embarrassing incident at Drakes birthday party two years ago.

Oh, I have the most amazing last-night-of-my-life-drinking story, the singer divulged in Complexs November issue cover story.

It was Drakes 30th birthday party, and I made quite a fool of myself. It took me weeks to stop doing this every morning I woke up, he said, appearing to allude to his heavy drinking. And then I had a conversation with myself. I remember where I was. I was in my sixth day of the hangover. Thats how big the hangover was.

Mayor then realized that drinking was limiting his potential, so he decided to make a change and sober up. And once he did, the skies opened up.

That next year, I did four tours, I was in two bands, I was happy on airplanes, he said. So what happens when you stop drinking? The level feels like boredom at first. But if you stick with it, the line straightens out and it goes kind of low.
