17. Pre-game with your friends and then skip the club.
Nights of debauchery don't have to cease now that you've decided to adhere to your new budget. If you can put in a few extra hours in the club by getting there before the door charges double, you're at the halfway point of cutting down your turnt up costs, but how about ditching the trendy nightclubs altogether?
We know you're a pro at pre-gaming, but make sure to do it at someone else's crib. Just get boozed up at your boys' house before everyone is set to head out and then feign a headache and go home when your friends go party. You'll have accomplished your goal of actually leaving your house during the weekend and getting lit, and done it all without spending any of your own money. If pre-gaming happened at your spot, you may have been expected to provide the spirits, and that's not how you keep your pockets deep.
