R&B star Solange Knowles was admitted to a hospital when she collapsed after downing flu medicine on a flight out of New York on Tuesday night. Beyonce’s younger sister was treated by medics after taking the capsules onboard a plane and suffering an adverse reaction to the medication. Her muddled mental state was laid bare in a series of bizarre postings on social networking website Twitter.com which she uploaded during the journey. But three hours into the trip, her messages suddenly stopped after she complained of feeling sleepy – and three hours later she logged back on to the website to tell fans: “Woaah…… How’d I end up in the hospital?” Knowles is believed to have been heading back to her home in Los Angeles after attending the opening of an Armani store in New York on Tuesday evening, according to reports. In a series of Twitter postings during the flight, she told fans how she had swallowed NyQuil tablets to treat a cold. She wrote: “I took a nyquil and i think maybe im getting high off it because im not sleeping. maybe i should close my eyes…” Minutes later she added, “think im certified loosing (sic) it on nyquil. going to sleep before i start freestyling on the plane… omg (Oh my God) i didnt know nyquil could do this to you. i took the pills tho. cant stomach cough syrup. trying to be proactive on this flight.” She then added: “Never taking nyquil again. I feel so weird.” The singer left further apparently rand om messages about various musicians and having “freezing” feet, before a break of three hours. She then logged on again and wrote: “Woaah…… How’d I end up in the hospital? Woke up to 8 rand om people over me, laid out on the floor in baggage claim!… Guess I passed out! Scary. Hooked up to IV now . Apparantly I’m super dehydrated. I’ve never passed out before. S**t was like the movies. People stand ing over me saying ‘hello’… My mom is the best. LOL (laugh out loud). She’s like ‘Ain’t nothing wrong with this girl, she need some water and rest… Pull up the car!’ LOL I’m like still in shock. I’ve never passed out before. Think it was the nyquil too. I felt weird when I woke up. This has been the day from hell. I’m done with the second IV. I just want to get in the bed and lay with (son) Julez. That’s all I want. The singer later confirmed she had been released following treatment, writing: “I’m out! yay!… they let me go….. Rest. Water. Rest. Water.
