it has already been said but i'll reiterate. take care of your mind and body and you can and will be fine. don't let your senses outwit your mind. think about what is goinig on and the state u are in before reacting to the things u hear and/or see. after a while the meth monsters become your friendly and amusing companions.
seriously though, it is NOT impossible to stay awake for 14 days, i have done it several times and go 5-9 days regularly. and i have for approx. 8 years. i have a set of rules to follow when doped and make myself stick to em. i eat every 4 hours, especially protiens and simple carbs, i take a multivitamin every day and a b complex on top of that, i drink water every 2 hours (4-8oz), i don't sleep but do meditate for 1/2 hour every day, if going for a long stint (7 days or more) i take a small dose of xanax, valium, or klonapin each day at the same time every day, this lets my muscles relax and shed some of the stresses that wear us out. i shower every 24 - 48 hours, brush my teeth 2 times a day, use eye drops every 8 hours or so, wash my hands and face with regularity, especially since i have facial hair. i do my best not to pick at my skin, when i do crash i try to always shower before hand. (it's the after sex crash that often prevents me from doing that tho) it seems like pretty basic and stupid stuff, but it makes all the difference in my opinion. for the record i have been using for ten years smoking for 8 and i never bang. i have no cavities, am slightly underweight, all my hair, no infections in 10 years as i have seen in many others. i rarely get sick and don't have a cough nor do i shake unless i've been up for 9 or 10 days. i'm not trying to brag, just point out that so long as you keep your body healthy in all the other ways u can, using dope regularly for a long period of time is not all that detrimental.
now i do have to admit that i have done iq tests on a day by day basis several times and i have found that i have scored a loss in iq for each additional day i was awake. if i was taking care of my self the slide was rather slow, (2-5 points daily) but if i was not eating or drinking enough water the slide was very high (11-14 points daily). incidentally i have never outscored my sober score when on dope. i have matched it, but never gotten a higher score.
