I woke up during the night feeling a little nauseous, but ended up falling back to sleep not thinking much of it. When I needed to get up for class at 9 and sat up in bed I got violently dizzy to the point of nausea. I stayed in bed a little longer only to fall back asleep and wake up at 10:30. At that point I got out of bed and made it half way to the bathroom only to suffer the same fate. As long as I remained laying flat on my back I felt perfectly fine, but I could not sit up without getting sick.
I was able to get a ride to the clinic around noon and the best part of the whole experience was making it half way up the steps only to get dizzy and have to lay down. Well that scared the shit out of the nurses at the front desk and completely by accident I got whisked right into a room past about 35 other people waiting in line. Fortunately no brain tumors or anything just case of what the doctor called vestibular neuronitis. So basically my brain spent a day at the amusement park on the tea cup ride while I was bored up the wall. I am better today, a little tipsy, but nothing I cant handle.
