It's called self-control
Lol. Been there, done that. Don't let everyone mooch off your alcohol. I learned that the hard way.
Honestly partying had little to do with my spending though; it was eating out that cost me the most. There were times when I was so lazy about cooking that I'd eat out almost every night.

I would say... You gotta chose. Are you gonna be a successful student or a passed out party animal?
Difference between will power and ill power.
yes self control and I know its hard to have because you get urges.
Buy the cheap, nasty beer on sale. 😁
