...This is amazing...
How are you seriously only spending 50k?

That boggles my mind.
On a regular night, around 70k. If I'm going a little crazier, upwards of 100k.
I'm wondering, how early (late) are you going in? I often won't crawl back into bed until 3 or 4 in the morning. And by that time, I'll have been at about four or five different places.
But, I'm not concerned about the money I spend. If I'm out, I'm out; no sense in pussyfooting around. If it's a matter of saving money, just do what I do. First thing after pay day, put the money you're going to save away. Take it out of your account. Put it into another account. Take that card or bank book and keep it hidden at home. Then go buckwild with the money you've left. That's your money. Do what you want. Seriously, easiest way to save money. You don't save money by adding the coins you've left at the end of the month. You save money by SAVING money. Take half your paycheck and put it away from you. The other half is yours to eat, pay bills, have fun.
Spend too much one month? Have no money? Sucks. Spend a week eating nothing but ramen or white rice and you'll fast learn how to not go crazy. When I first started working in Korea, I was blowing through 1.5 million inside of 2 weeks (bottle service, buying shots, having sushi [not rolls, I mean that the guy carves for you and your date at your table], nice clothes). Yes, it was stupid fun. But then, I'd wake up and realize, "Well, I suppose if I want to pay for my phone, internet, electricity, etc I'll have to eat white rice for a week before my next paycheck."
Didn't save a single cent that year.
But, now, I throw a grand into my savings first thing. I throw an additional 100-200 into another checking account as well. That still leaves me with plenty of money. It also helps that I don't go out nearly as often (I'm living in a much more rural area). But, when I do go out, I go balls to the wall. I eat, I drink, I treat myself and others.
Want to save money? Put it away.
