Okay, so since I'm an experienced No-Lifer I decided to share my methods that makes me able to play 19/7 whenever I'm able to. so here are the req stuffs you will need to have.
1. Food, this is really important because you will get hungry after No-Lifing for a certain amount of time. TIP! : Do NOT eat turkey, bananas, or drink milk, eat Peanuts. These contain tryptophans, a precursor for creating melatonin which makes you fall asleep faster.
2. Entertainment. I suggest watching a Movie while No-Lifing at the computer because even No-Lifers get's tired of MapleStory.. after 15 hours you will just wander around in Henesys like a zombie with nothing to do, so I suggesst having a comedy movie or horror movie to stay entertained.
3. DRINK/EAT Coffein. Coffein is really important, because this will help you stay awake for longer amount of time which means you will be able to No-Life even longer. Personally I eat coffee because I usally don't think I have enought time to make with water. energy drinks will also work but it has alot of sugar and sugar + No-lifing = Diabetes 1 & 2 which is nothing good to have.. and also on some people energy drinks has negative effect like : Hyperactiveness or you could become really emotional and start crying if you die In MapleStory because you don't think you deserved to die. and also the hyperactiveness might wake up your family members if you live at home, which is bad because they will make you log out and that equals D: .
4.have light in you room, because you might become nearsighted if you are playing in the dark, and that's not good because you will eventually turn in to a zombie with Pink Glasses. (not meant to harass people with glasses)
5. eat grapes. Grapes contain some kind of Sugar that makes your brain able to consentrate more, this will help alot when your tired and for example you are killing zakum and it's almost dead and you fall asleep/aren't fast enough to pot. dying at bosses = D:< .
6. cover your windows. if they are not covered nearsighted Zombies might come and eat your brain which will make you transform into a Zombie. and also for werewolves I suggest doing this when it's full moon because you don't want to change at that moment.
7. if your not watching a movie listen to music. Music makes the gaming give more sense which will help you to keep on playing for longer time.
8. really important! be unsocial. if you are social you will have friends constantly calling you when your busy, and you will have to go outside! that equals FAIL!
9. don't watch Jonas Brothers. The Jonas Brothers gives you bad influence for a reason I can't explain.
10. you should have a pet. pet's calms you down when your raging about dying and losing 10% exp.
raging will make you depressed and attract Dementor's from Harry Potter that will eat your soul.
11. do NOT sit in a chair with the computer if you have a laptop you will slowly go steril and become a zombie. I suggest a chair with a table infront.
12. if you are on your computer long enough it will come radi active stuff out of it and your private parts might mutate... Example : Your Noodle <--- child friendly. might mutate into tentacles and strangle you at night and if not they will attract zombies that will eat your brain, and you will become the ultimate Zombie with strong tentacles that can lift like 500 ton's.
so this was my guide... it will constantly be updated. enjoy your No-Lifing! :D
