My summer job was the kind of job where it's slow during bad weather, and fast during good weather. So, Canada day rolls around and only the friday or saturday, whatever day it was, I worked a 12 hour shift, got home, showered, and headed to a Canada day party at my friend's house. Party was broken up around 1am but I stayed behind with my friends and we drank til the wee hours of the morning, and when I'm drunk I get hungry and eat whatever but I have a really bad stomach so I can't eat greasy food and stuff like that, and I ended up having a couple pieces of pizza, cold hot dog, and cookies. Oh man, so sick the next day.
Probably about 4 times over the summer I'd work a 12 hour shift one day, party at night, get 2-3 hours of sleep, and work a 13 hour shift the following day.
This upcoming summer, I'm finding a job where I don't work weekends.
