Hey who has beat the MAIN quest? It was kinda short for me. I stayed up till 2:30 AM for the last to days playing NONSTOP. I got the game the day it released(11.11.11) and I started playing it at 4:30 PM. So anyways. Now what do I do?

Ive got so many side missions i cant tell what the main quest is anymore...

I got it at midnight and beat it on Saturday. Do all the guild quests and dark brotherhood, find all the stones that give you powers, look for all the shouts, etc... I have at least 20 quests in my queue right now just from talking to random people.
