I vomited in my 300+ student filled lecture hall
Why did you vomit in the lecture hall?
I was drunk and couldn't keep it down.
It shows a lack of self-control to go to a lecture so drunk that you throw up. If you feel the urge to throw up, it is best to get to a restroom so you aren't vomiting in public; most people find that gross and distasteful. You should consider not drinking before lectures other and important events.
It's my first time ever vomiting in a public place. I was going to wait till I got home but I couldn't wait.
You shouldn't put yourself in such a situation, then. Learn from this and avoid dinking so much in the future.
