This happened when I was first diagnosed with strep throat mixed with a bad cough back in my junior year of high school. The doctors ended up prescribing me Vicodin and codeine syrup I believe and when i took it at my house I immediately went to take a nap and get my rest. But when the weekend passed I was getting ready for a dreadful Monday day of school, so I took a prescribed dose of both vicadin and codeine and went to school not knowing what was about to occur. When I arrived to school I went straight to the band room to begin my first 2 periods of class. The director started lecturing but soon English became an unrecognizable language to me and I was left dumbfounded looking at my cousin like wtf is he saying. (Next to me since we're both in the trombone section) I start loosing focus and luckily our band directer lets us all go and "practice" our music in sections. Since I couldn't play I was left to conduct my section with common 4/4 hand time. As soon as I sat up to conduct I felt as if I was looking in third person and lost my balance so I started to back peddle as I was stopped by the wall on the hallways as I fell on my ass. I didn't feel any pain whatsoever and voices started to grow louder but still unrecognizable kind of like the Charlie Brown Cartoon. Luckily none of my section told our director what happened and my cousin ended up dropping me off at home, and that was by far the funniest, but scariest day I've had in school to this day.
<bot>: Took medicine without knowing that it makes you high before school started, fell on my ass, and left home after an hour of school.
