When I played sports... football and basketball... basketball in college... I used to drink heavy. Once I started competing and doing photo shoots, I couldn't do it anymore. I'd diet for 3-4 months and not have a sip. Then after I was back to off season, I'd go out and a cpl drinks would have me fucked up. I used to be able to go to practice and play hard on almost no sleep without even a headache from the night before. Now getting drunk puts me out of commission for a solid day or 2 to follow. So once I started equating booze with suffering as opposed to a good time, I lost interest.
