There used to be these energy pills called RED CAPS, 950ML of pure efhedra, at the time i was working 3 part time job's
getting about 3 hours of sleep a day, worked all 3 for about 3 months, kiked back to just two, Auditor at UPS and Construction cleanup, but stayed with the 3 hours of sleep a day and lived on thoes pills, they were store bought, so no fear right? nah about 9 months later started haveing chest pain, 2 stroks and 1 heart attack in 1 month, at 19.  Cause 1800MG of ephedra a day, washed down with a 6shot mocha and mountain dew working sunrise at UPS, lasting effect to this day jitters,  side effect Heart wise medication, to lower blood viscosity,   lesson learned,  just because its legal does not mean it is not harmfull.
now I stay away from any type of energy boosting additive, I drink a sparks now and again, a mocha in the morning and nountan dew during the day. nah just sleep, heartattack is scarry as hell.

It's amazing you're still alive. With 1800MG of ephedra a day in you,  I dont see how you kept from bouncing off the walls

Aye they did a blood test, the though i was on meth, they only found ephedra, non of the other agents then they started believing me, but they can make a picture of your heat with electrodes they stick on you, said i have a strong heart, now i get palptations every once in a while, and chest pains, thats what the meds are for, but daily max dose of ephedra is like 450MG or somthing like that, so one pill puts you at 2x the max daily dose.  They of corse dont make the pills anymore.  but words of warning to ppl looking for a boost, it can and will catch up to you if abused.  And i came pretty close to death, I rember it verry well, my chest started to hurt, then my arms and legs got numb, bout that time my legs gave out and I hit my head on the concrete,  i rember wakeing up in the hospital. feels like somone riping your heart out through you chest, i am just luck because my "now wife" had only just walked through the door when it happened.  and she called the ambulance,  so yeah I came close to not bieng around and it makes you think.
sorry to steal the threed,
i find that to keep my self awake on jobs like that, Mountain dew, maby a sparks or 2  and get plenty of sleep the night befor, hit it as soon as you get it and go full bore. have everything ready first , and handy good luck and keep us posted,  but i dont think putting your body on overload will help its easer to think when your head and you arms move the same speed.  less mistakes - and you only have time to do it once.
