It looks like a typical birthday dinner, but there's nothing typical about it. Hanna Lottritz is turning 21. 

She celebrated with her friends, and her baby sister Sarah at Tha Joint Sushi in Spanish Springs. There's nothing special about the sushi, the talk about boys talk is normal too, but there's an incredible story behind that one glass of sake Hanna is drinking. 

At Night in the Country in July Hanna and a friend got into a competition. 

"It was a chugging contest," she said. 

A drinking competition. 

"He threw up."

Hanna passed out, and needed to be flown by Careflight to Renown Regional Medical Center in Reno.

She spent the next 24 hours in a coma. The doctor, her parents, and her sister didn't know if she was going to live.

"They were terrified," she said. She spent three days at Renown, before being discharged.  

"It's surreal, thinking about what could have happened."

And it's even more surreal to think about what happened next. 

"Greetings from Belgium, the Netherlands," Hanna reads online. "It has been insane."

Hanna shared the experience online, hoping that by hearing it, one person's life could be saved. 

"If I can help one person by sharing this story, I will be absolutely ecstatic," she wrote on her blog. There are more than 300,000 views on her page, not to mention dozens of smaller, and larger sites, including the Huffington Post, picked it up. 

"It's been written in other languages." 

She is not proud of what happened, by any means. But she is happy that her story is being shared around the world. But the person who she probably made the biggest impact on, is her sister, who says she's not going to drink.  

"I don't know what I would've done if I didn't get to say goodbye to my sister," said Sarah. 

So even though Hanna is another year older, she is definitely another year wiser...and then some.   

"I shouldn't have woken up from from this."

Hanna is currently studying journalism at the University of Nevada, Reno. Here's a link to Hanna's blog post, if you want to check it out for yourself.
