She was just suffering from dehydration after not drinking enough water at the beach.
“The beach yesterday was definitely worth my trip to the ER last night from dehydration afterwards,” Kailyn tweeted on June 23. “I’ll just drink water all day next time.”
But, according to another tweet, Kailyn did spend the night throwing up.
“Yeah, I was throwing up all night. It was awful! But a lot better now! It was good seeing you!” she shared.
