<human>: This started out because I like to eat/drink ketchup by itself sometimes just as a snack and my friends decided to make a challenge out of it. The challenge was that they'd bring in as many ketchup packets as they could and I'd drink them at the end of the year (today).

 I had expected maybe 30 or so but thought they would forget about it. Now I have 68 ketchup packets in my bag that I'm supposed to chug in about 3 hours. I know there's likely some safety concerns about this but how dangerous is it exactly? 

We've laid down the rule that if it becomes a serious concern to my health I wont do it so I depend on reddit to give me the go code. I've already checked google but couldn't find anything.

Can you give me the gist of the text in a nutshell?
