Before you ask how to get through a two-day all-nighter (are you MAD?), you should think hard about just how much of your health you're willing to sacrifice for this project. Sleep deprivation is NOT the minor inconvenience that people treat it as. You are impairing nearly every system in your body, and doing damage, some of it possibly permanent or long-lasting, to your cognition, memory, and all those subtle processes that separate you from insanity. Also, people die from it, usually indirectly but sometimes directly, and sometimes as a complication with other problems (like those people in internet cafes you hear about every few years).
If you're already short on sleep, you probably shouldn't do it.
Caffeine works, but only up to a certain point, and then it just leaves you feeling drained. Also, it causes irregularities with your heartbeat, which you've already noticed. Also, eating sugar is bad advice based on a myth that has been discredited for at least a decade. Complex carbohydrates (breads and starches) might be helpful, but simple sugars are not. The body's usual response to a spike in blood sugar is to increase the amount of insulin in the blood, bringing it back down, possibly below the starting value. The hyper kid thing is bullshit. The kid's hyper because it's a kid who's been told it's about to get hyper under mitigating circumstances; the kid is not hyper because of the sugar.
Finally, expect to work slower and make more mistakes. I found that it's far more productive to just sleep regularly because when I worked 16-19 hours a day, my working hours weren't worth as much as they used to be. Eventually I got to a point where I was getting four hours' worth of work done in nine hours.
Long story short: our culture doesn't place much value on sleep. This is one of those areas where our culture is absolutely and irredeemably full of shit. Pay no attention to it and do what your body is telling you to do instead. I've been there (5 hours a night or less for two or three weeks) and I'm here now (8 hours a night), and I can tell you that here feels better and is more productive.
It turned out in the end to not require a double all-nighter! I finished before I expected and managed to get some shut eye last night. I imagine it was not enough, as I still feel reallllly tired, but I was surprised and happy to get any.
It's not a method that I am endorsing on any reasoned basis, just trying to get my work done in the time I have. I really shouldn't of left it so last minute, but I wasn't even aware until a couple of days ago that this particular project was due a month before the other two, so had to take drastic measures.
To be honest, after the 3rd/4th can of energy drink, I really couldn't bear the idea of drinking them anymore and actually stopped midway through a can. I couldn't make myself have any more of it, so the last few hours I did 'sober'.
I will make a concerned effort to be less of an idiot next month and not to do this to myself again.

After a certain point, you will stop being tired. A similar phenomena happens when you choose not to eat or go to the bathroom - the urge to fulfill your bodily functions goes away.
At this point, you're living on borrowed time. Streamline everything: Get your work done as quickly and efficiently as possible, hand it in as soon as possible, do EVERYTHING you need to do immediately. As soon as everything is taken care of, go to bed immediately, tired or not.
The "Sleepy Rebound" is a truly terrifying and soul-killing experience (especially if you're prone to night-terrors - think of the "micronap" moments in the newest Nightmare on Elm Street), and it can strike at any time after you've stayed awake for so long that you're no longer tired. The only way to survive it unscathed is to be asleep when it hits.
Warning: You'll feel like you got hit by a truck when you wake up. It'll go away eventually.
To be honest, I'm not sure if I ever felt this serene stage of no longer being tired. I felt happy and fulfilled once I had finished and that was a nice refresher, but I knew I was still needing of sleep, so turned in asap. Not quite the double all-nighter I was expecting.
It felt awesome to get into bed, almost worth doing more all-nighters just to recreate that feeling, but I definitely am feeling it this morning, as I did get some sleep, but evidently not enough.

Done this plenty of times myself. Avoid sugar, and only caffeine when absolutely necessary. If you need increased alertness for possible danger or finishing up/editing.
Take a few minutes to turn off stimulus and determine if it is worth continuing. Often it is not.
This really beats up your body. I quit doing it last year.
It got to the point where I couldn't stand having any more of the sugary/caffeine energy drinks. Couldn't stomach the idea of any more of them, so had like a few hours of nothing, before turning in and getting some sleep.
I think the coffees are actually a better move than the energy drinks, but for some reason I have a thing in my head that tells me to get energy drinks in for project nights and it has become part of my prep, so I have to do it. I still have half of the cans "undrunk", but had to do the act of buying them.
