Techincally yes. It was a combination of exhaustion/dehydration. But I have so many medical problems to begin with, that I am very susceptible to these things. It usually happens just from pushing myself too hard and not drinking enough.
The last time was because I tried to push myself through an illness (it was midterms) and my body just finally gave up. I couldn't stay awake, I couldn't eat anything, and I couldn't drink anything. All I could do was sleep. My mom took me to my internist and I slept the entire 2 hour drive there and I was falling asleep while in the office and she said that I just really LOOKED sick. My blood pressure was low, I was having severe PVCs, and my heart rate was all over the place. I didn't feel sick...I just felt exhausted. I was in the hospital for 4 days getting rehydrated and IV nutrition while I slept. I spent another 4 days home resting before going back to school. I felt about 100x better when I got out of the hospital. But I've gotten much better about not pushing myself too hard but thats difficult as a college student.
But for me, it works when needed (It's happened about 3 times in the past 8 years). I wouldn't say hospitals are relaxing, but I do actually get a lot of sleep. I can sleep through pretty much anything (IVs, blood draws, etc)
