You only need rest,2 weeks aint shit I know people that more or less dont sleep at all.To stay occupied we would be out doing shit clubbing,casinos selling drugs, cooking,stealing chemicals and working on cars.When i say no sleep I would lay down for a few hours or so but never sleep.The fatiuge and lack of food and sleep depravation catches up with you.I have collapsed a few times.Its hard to eat so I always had multivitamins and would occasionally eat something easy to chew like a bannana or a yougurt or milo to keep me going.When I would come down I would sleep for 3 days only waking once or twice to piss or have a drink.This is no bullshit and there are alot more people out there with bigger habbits.I am of the shit now and even thinking about it depresses me .You also get meth rage wich really is hard to deal with.
