It's possible man, i did it a few weeks ago. Just jump on, and keep going. Sandwhiches for lunch and dinner, eat while you play. If at any time a voice at the back of your head starts telling you to leave the house, put headphones on and turn the lol sound up.
I started Friday night, finished Sun, back to back playing, 6-8 hours sleep. Sat i won all day cos i was pumped, Sun i was defeated all day cos i'd lost the will to live.
Virginity is not virtue, it's just lack of opportunity.
