The young woman named Mita Diran was a copywriter for ad agency Young & Rubicam.
On Saturday she tweeted "30 hours of working and still going strooong."
Gawker reports points out this is the second death of an ad-agency worker in the past few months.
She died the next day.
Buzzfeed reports Diran's father blamed her death on "too much Kratingdaeng." Kratingdaeng is "Thai Red Bull," also known as the original Red Bull.
Earlier this year 24-year-old Li Yuan died after spending a month working from morning until at least 11pm.
