After having a good drink and a lot of fun, you should have a place to go back to and have a good sleep. There are not so many cheap hostels in Moscow, but you can choose one of these Napoleon Hostel, Home Hostel, Trans Siberian Hostel, Yellow Blue Bus Hostel or Home from Home Hostel (average cheapest room $25). If this price does not work for you, you might want to try one of those hospitality social networks like HospitalityClub or CouchSurfing. These networks fuse a number of fantastic opportunities altogether: free stay, new friends and better understanding of a new culture. Russian hosts are very hospitable, they are likely to take you around the city and show some of their favorite places, teach you some funny Russian words and might even show you how Russians really drink.
