Li Na said if she won the US Open, she would not ruin her champagne moment by overdoing the celebrations.
In January, the Chinese star woke up with a thumping hangover following her Australian Open fourth-round defeat to Kim Clijsters in a match where she squandered four match points in a 4-6, 7-6 (8-6), 6-4 loss.
"It was really tough. For me it was worse because the next day was Chinese New Year," recalled Li. "After I lost the match, I was like, 'What was going on'? So I was like, 'OK, just take the beer and [get] totally drunk'."
The 30-year-old Li was adamant that any success in New York would be celebrated calmly and in moderation.
"Fortunately I [do] not do the same," she said. "Maybe a couple of beers, but not all the time."
Li reached the US Open third round with a 6-4, 6-4 win over Australia's Casey Dellacqua.
